IMG.LY vs. Printess
The Printess alternative for teams that want a print-ready design editor they run themselves: on the web, in native mobile apps and on their own servers.
What makes IMG.LY the best Printess alternative?
Your servers, your data
Run the editor and its rendering in your own cloud, in a private cloud or on-premise, so designs, uploads and customer data stay in your infrastructure.
Native iOS and Android editors
The same engine runs in native iOS and Android apps, in the browser and in Node.js, so a template renders the same wherever it runs.
PDF/X for any press
Export PDF/X-1a, PDF/X-3 or PDF/X-4 in the browser or in Node.js with your printer’s own ICC profile, plus crop marks, bleed and cutout lines.
Design tools for your AI agent
With the CoDesign SDK, the AI agent in your own product creates finished, on-brand designs, and users refine them in the editor with all text still editable.
What our clients say about us
Integrating IMG.LY’s editor meant we didn’t have to build or maintain a complex editing layer ourselves. That kept our team focused on our core AI ad engine and saved us countless development hours — while still giving our customers the ability to polish and customize creatives at scale.
Hikari Senju
CEO, Omneky
With IMG.LY we built a central creative portal that now powers over 140 dealer campaigns across multiple automotive brands. Before this, asset creation was slow and inconsistent.
Martin Röhr

IMG.LY vs. Printess at a glance
| Feature | IMG.LY | Printess | Notes |
|---|---|---|---|
| Primary Use Case | An SDK for putting a print-ready design editor and automated print-file generation into your own product. One extensible engine handles design, print and video work, both in the editor and headless. | Web-to-print personalization platform where shoppers customize products such as photo books, cards and engraved items, and Printess turns each order into print-ready files. | IMG.LY covers web-to-print personalization plus video editing and design work beyond print. Printess focuses on personalized print products sold through shops. |
| Target Audience | Print businesses adding personalization to a platform they already run, from commercial printers with ordering portals and print-on-demand services to photo and gift shops, packaging and label makers, and brand portals. | Online shops, print businesses and B2B portals selling personalized print, with designers building templates using little or no code. | Same buyers on both sides: print businesses, shops and portals selling personalized products. |
| Technical Approach | A modular SDK you deploy on web, mobile, desktop and backend servers. Use the ready-made editor, build your own interface, or automate without a UI, all on infrastructure you control. | Hosted cloud service: shops embed the editor as a web component, designers work in the browser-based Designer Side, and backends call a JSON API for production. | IMG.LY deploys on web, mobile, desktop and server under your control. Printess runs as a hosted cloud service that shops embed. |
| Advanced Design Editing | Vector, text, image and layout tools built for print, with CMYK, spot colors and print specifications. Multi-page documents keep precise typography, and the editor and automation render them the same way. Text runs along a path on web, mobile and desktop, and in the web editor shapes can be edited point by point. | Frames hold images, text on a path, barcodes and Bezier-edited vector shapes, with shadows, glows and gradients. Text supports OpenType, colors can be RGB, CMYK or LAB, and documents can have multiple pages. | IMG.LY covers layout, text, vector and color work for multi-page print designs, including text on a path and point editing of shapes. Printess offers the same core tools, and its frames hold QR codes and barcodes such as EAN-13, Code 128 and Data Matrix. |
| File Format Support | Handles PDF, PDF/X, JPEG, PNG, WebP, SVG, MP4 and its own template format on import and export. InDesign (IDML) and Photoshop (PSD) files come in with their layers, EPS and Illustrator (AI) artwork becomes editable vectors, and designs can go back out as IDML, or as PSD on the server. Interactive and automated exports render alike. | Imports common image formats, PDF, zipped IDML packages and Illustrator artwork pasted from the clipboard, and outputs PDF, PNG or JPG, with GIF and MP4 when animation rendering is on. PSD import is not documented. | IMG.LY round-trips InDesign IDML files, and Photoshop files too when exporting on the server. Printess keeps every layer of a pasted Illustrator graphic editable in its path editor and accepts TIFF and HEIC uploads. |
| Print Production | PDF/X-1a, PDF/X-3 and PDF/X-4 export in the browser or in Node.js, using your printer's own ICC profile, and a check reports PDF/X rule violations before a file goes to preflight. Exported PDFs carry trim and bleed boxes, CMYK and spot colors, and cutout lines for die-cut products. In the web editor's Print Setup panel, users add crop and registration marks and set bleed per side, and on screen CMYK looks the way it will print. | Print files carry color-managed CMYK, named spot colors, overprint, bleed, cut contours and white underprint, and can be forced to PDF/X-4. Saved impositions add crop marks and slug, and files can go straight to HP Site Flow, KornitX or FTP. | IMG.LY exports PDF/X-1a, PDF/X-3 and PDF/X-4 in the browser or in Node.js and checks files against PDF/X rules. Printess lays out impositions, hands files to print providers and can preflight buyer PDFs through an Atomyx account of your own. |
| Templating & Dynamic Editing | Placeholders, text variables and lockable elements turn a design into a template whose layout adapts to the content that fills it, and you set editable regions and parameters in JSON or through the API. Manual and automated runs share one structure. Exclusion areas keep content off spines, envelope windows and die cuts, and a safety margin guide appears when users move content near the page edge. | Design Templates merge into Base Templates that hold a product's print setup. Form Fields drive Styles that change any property, Layout Snippets swap layouts, and a safe zone marks where frames could get cut off. | IMG.LY builds templates from placeholders, text variables and lockable elements and keeps content off spines and die cuts with exclusion areas. Printess builds them from form fields, styles and layout snippets, with a safe zone at the page edge. |
| Variable Data Publishing | Real-time and batch variable data runs use the same templates customers edit, and capacity grows with the infrastructure you run them on. | Production calls render the document once per record into one file, and depending on the plan, buyers can add records in a table and templates can read a Google Sheet. | IMG.LY runs real-time and batch variable data on the templates customers edit. Printess renders one design per record and, depending on the plan, lets buyers add records in a table. |
| Creative Automation | With no one in the editor, a headless engine on Node.js fills templates from your APIs, databases or spreadsheets and renders personalized print files at scale. | Backend calls create designs from your data, applying form values, merged templates and images from URLs, then render print files with no buyer involved. Remote-controlled templates can change a buyer's design at production time. | IMG.LY fills and renders templates in a headless Node.js engine. Printess creates and renders designs through its backend API. |
| AI Capabilities | Image generation, background removal and text refinement come as AI plugins that work inside the editor, with requests that can go through the AI Gateway. With the CoDesign SDK, the AI agent in your own product produces finished, on-brand designs that users open in the CE.SDK web editor, where their text stays editable. | Buyers get AI image generation and edits, background removal, face swap, upscaling and AI text, and two design agents are in beta, one of them on request. Design tools for your own AI agent are not documented. | IMG.LY pairs AI plugins with the CoDesign SDK for your own AI agent. Printess offers AI tools for buyers, and its two design agents are in beta, the buyer-side one on request. |
| Product Mockups | The Mockup Editor starter kit previews designs on apparel, postcards, posters and business cards, and the 3D Mockup Editor starter kit pairs CE.SDK with 3D libraries for real-time product previews. Both run on the web. | Perspective and mesh warps build photorealistic previews, and 3D previews use uploaded GLB models. The Mockup Service API renders designs onto other products, the Account Portal does it in batches, and 3D previews and the API depend on the plan. | IMG.LY previews designs in 2D and 3D through web starter kits. Printess offers 2D and 3D previews too, plus a mockup API and batch generation in its account portal. |
| Asset Management | Connects to your DAM or any custom asset source, and product photos, logos and artwork stay in your own infrastructure, under your ownership and control. | Images, fonts, snippets and 3D models live in your Printess account, and shoppers' uploads persist between visits. Images from a DAM or CMS are copied in by URL. | IMG.LY connects to your DAM and keeps assets in your infrastructure. Printess stores assets in your Printess account and copies DAM images in by URL. |
| User Interface | Ships a ready-made editor you can customize, plus APIs to build a fully custom interface or embed only the parts you need, in the editor or headless. | The Panel UI is the full buyer editor with desktop and mobile layouts, the Slim UI (depending on the plan) edits simple products on the product page, and a JavaScript API supports your own interface. | IMG.LY lets you rearrange its editor UI piece by piece or replace it entirely. Printess can reduce its editor to a bare viewport through its JavaScript API, for a UI you build. |
| White-labeling | No IMG.LY branding in the editor, and the interface, themes and components can all be restyled for OEM or enterprise products. | Depending on the plan, the Theme Manager restyles panels, colors, icons and backgrounds and puts your logo in the editor and on the loading screen. | IMG.LY ships with no branding of its own. Printess restyles its editor and swaps its logo for yours through the Theme Manager, depending on the plan. |
| Interactive Editing | Edits appear in real time with GPU acceleration, and a design looks identical in the browser, on mobile and on desktop. A Design Validation starter kit for the web warns users when a design is not print-ready. | Buyers fill forms, follow guided steps that zoom to each element or place stickers freely, and the editor validates every field and frame before checkout. | IMG.LY lets users work directly on the canvas and points out print problems in the web editor. Printess can steer buyers through forms and guided steps, and any error opens a dialog that stops the checkout. |
| Multi-Layer Editing | Stack any number of image, text, shape and video layers, then blend, group and mask them. In the web editor, a layer and page list lets users reorder, rename, hide or lock any element. | Named layers span all pages, with separate print and buyer visibility and per-layer locking, and frames can be grouped, masked and blended. | IMG.LY stacks, blends, groups and masks layers, and its web editor adds a layer and page list. Printess layers span every page of a document, and frames take opacity and blend modes. |
| Cross-Platform Support | Runs natively on the web, on iOS and Android, on desktop through Electron and macOS, and in Node.js on the server, and renders identically on all of them. | Runs in desktop and mobile browsers, and iPhone and Android apps embed it in a WebView, with sample projects for both. Native mobile or desktop SDKs are not documented. | IMG.LY runs one engine natively on the web, iOS, Android, desktop and the server. Printess runs in browsers, and apps embed it in a WebView. |
| Customizability | Creator, Adopter, Viewer and Presenter roles decide who may edit what, and configuration files, APIs and plugins shape workflows and UI layouts. | Per-frame settings decide what shoppers may move, resize or change, per-template settings tune the buyer UI, and load-time parameters set the start state and basket flow. | IMG.LY sets permissions with Creator, Adopter, Viewer and Presenter roles and shapes the UI through configuration and plugins. Printess sets permissions per frame and appearance per template. |
| Extensibility | Plugins add tools, asset sources and rendering steps without changing the core SDK, so upgrades keep working. | Template scripts add dialogs, panels and buttons in the buyer's browser and react to events such as checkout. The Shopify integration has a plugin system. | IMG.LY extends tools, asset sources and rendering through plugins. Printess extends templates with scripts, plus a plugin system in its Shopify integration. |
| Ease of Integration | Documentation and reference implementations cover every platform, and the evaluation gives you the full SDK, the same access as an enterprise deployment. | One script import, a shop token and a template name load the editor, which returns a save token when the buyer adds to the basket. CodePen samples cover frontend and backend. | IMG.LY backs each platform with documentation and reference implementations, and evaluation comes with the full SDK. Printess publishes integration skills for AI coding tools. |
| E-commerce Integrations | Sits inside your existing shop as its design editor, on Shopify, WooCommerce, a print platform or your own build, while your shop system keeps handling catalog, cart, payment and fulfillment. | Plugins for Shopify, WooCommerce, Magento and Shopware map variants to form fields, reopen cart items and pass orders to production. Amazon Custom orders become ready-to-produce designs, and Bubble.io has a plugin too. | IMG.LY embeds as the editor in the storefront you already run, and your platform keeps the catalog and checkout. Printess ships plugins for Shopify, WooCommerce, Magento and Shopware, and turns Amazon Custom orders into ready-to-produce designs. |
| Flexible Rendering Approach | Render on the client, where the device GPU drives interactive editing with local data, or on Node.js servers with the CE.SDK Renderer for automated generation. One engine produces pixel-identical output in both, so you choose by use case. | Previews draw in the buyer's browser, while print files and API mockups render on the Printess backend. Rendering print files on infrastructure you run is not documented. | IMG.LY renders on the client or on your servers with the same engine. Printess draws previews in the browser and renders print files on its own backend. |
| Production Readiness | Runs in enterprise deployments that generate millions of assets a month, and support comes in tiers that include help during integration. | Printers, agencies, corporates and product vendors in Europe and North America run Printess as a cloud service, with plan-based SLAs, an availability commitment, GDPR compliance and encryption. | IMG.LY runs at enterprise scale on infrastructure its customers control. Printess recommends a tested stable version for production use. |
| Scalability | Load balancing and asynchronous rendering spread work over clients and servers, and batches have no size limit. | Production jobs queue, run asynchronously and report back through callbacks. Failed orders can be requeued, and callbacks retry if your endpoint is down. | IMG.LY scales across clients and servers with no batch size limits. Printess throttles status checks on production jobs and asks for callbacks when many jobs run in parallel. |
| Storage & Data Ownership | Designs, uploads and customer data stay in your infrastructure, and nothing depends on external storage or a third-party service. | Templates, designs, uploads and output live in the Printess cloud, designs can be deleted on request, and uploads can go to your own S3 bucket. Self-hosting is not documented. | IMG.LY keeps data in your infrastructure. Printess stores designs, uploads and print files in its cloud, and buyer uploads can go to your own Amazon S3 bucket instead. |
| Clear Pricing Model | Licensed per deployment scope and usage volume for enterprises. The evaluation includes the full SDK and sets no user limit. | Monthly or annual subscription priced per order: each tier includes order credits, and overage, some modules, AI usage, API mockups and support hours cost extra. | IMG.LY licenses by deployment scope and usage. Printess sells subscriptions with per-order credits and paid add-ons. |
| Support & Documentation | Documentation and developer guides for each platform, backed by enterprise support with engineering consultation. | A knowledge base, Academy video courses and API references with live test requests, plus email and chat support and paid training. | IMG.LY pairs platform guides with enterprise support and engineering consultation. Printess puts context help on almost every tab of its platform and publishes TypeScript definitions for its API. |
