Who it’s for Print shops
Product personalizer for print shops. Your customers design the job. You get the press-ready file.
For print shops, photo labs, sign shops, framers, trophy and engraving shops, and brands with a trade printer. Each personalised job arrives as a file at your template’s exact size, colour-managed, with bleed and crop marks when your press needs them.
Files your press expects. At the size your template says.
PDF/X-4, colour-managed
CMYK, separated through the FOGRA39 or GRACoL 2013 press profile, which the PDF carries as its output intent, on a transparent background.
Bleed and crop marks
Up to 3 cm of bleed for each print area, with photos carried on into it, and trim marks outside the bleed. Nothing inside the trim moves.
Black text on the black plate
Pure black text can print on the K plate alone, overprinting, so a slightly misregistered press leaves no colour fringe around it.
Cut lines and white ink
A vector cut line traced from the product’s shape, and a white ink plate under the art or the whole shape, each as a spot colour you name.
Clipped to the product’s shape
Photos are clipped to each print area’s shape as the customer saw them, and run on into the bleed past the cut.
The resolution you set, checked
Files at 72 to 600 PPI, 300 by default. Customers are warned about photos too small to print well, and each file shows its lowest photo resolution.
These are standard file types, but RIPs and press software differ, so run a test file through yours before you take orders. Every file type, and what each suits →
Every job arrives complete. No retyping from an order note.
- A print file for each print area: download one, a zip per item, or a zip of the whole order.
- The proof the customer approved before checkout, and what they typed and chose, in the fonts and layouts it printed in.
- A job sheet in the order’s zip: a page for each personalised item, with a QR code back to the order.
- Each file’s print size, resolution and lowest photo resolution, with a warning when a photo is low resolution.
- A CSV export of your orders, including a fixed-column layout for merge software, and Mark printed as jobs are done.
- Make this file again: remake a paid Shopify order’s file in the product setup’s current print settings, or exactly as printed, while the order keeps its photos (90 days).
Orders from your website, inbox or counter. Two ways.
On your Shopify store
Customers design on your own product pages, theme or headless, and pay through Shopify’s checkout. The order and its print files arrive when it’s paid.
With Kastomise Hosted links
No Shopify store, or no online store at all? Send the link by email, put it on your website or a listing, or open it at your counter. Customers save their design and give you its code; you look it up and print.
Connect your production system. Webhooks and an API.
Files-ready webhooks
Add up to 3 HTTPS endpoints. When an order’s or a hosted design’s print files are ready, each one gets a signed event with links to the files and what the customer chose.
Orders, designs and files API
List orders and hosted designs, download their print files and mark them printed from your own software, with keys whose permissions you choose.

Print shop FAQ What print shops ask.
Your templates, the files, orders that don’t come through a website, and connecting your own system.
Who is Kastomise for?
Businesses that make personalised products themselves: makers who print, engrave or cut in-house (sublimation, DTF and DTG, UV, laser engraving or vinyl), print shops and photo labs, sign shops, framers, trophy and engraving shops, and brands whose trade printer prints from their files. Kastomise gives you the print files; it doesn’t print or ship anything, and it doesn’t connect to print-on-demand services.
Can I use my existing print template?
Yes. Send it with a setup request: a dieline or your supplier’s template (SVG, PDF, AI, EPS or an image), a spec sheet, or just a product link. We build the product setup from it at its exact sizes, as a fixed-price service, and check it against your spec before you review it. To build it yourself, type your template’s sizes into the editor: every print area, photo slot and line of text is measured in centimetres, and you can also drag them into place on the editor’s canvas, which measures in centimetres too.
What file do I get, and will my printer take it?
A print-ready file for each print area of every order, in the format you choose for each product setup: a CMYK PDF/X-4 with a transparent background and the FOGRA39 or GRACoL 2013 colour profile embedded, a transparent sRGB PNG, an sRGB JPEG on white, a laser SVG or PDF, or a cutter SVG for vinyl that also downloads as a DXF. Laser and cutter files are at true size in millimetres, with text as outlined shapes. Any file can be mirrored, and the PDF, PNG and JPEG can have bleed. The PDF can also have crop marks, plus a cut line and white ink in spot colours, and a PNG can be an engraving file, with text in solid black and photos in greyscale. Images are made at the resolution you set (300 PPI by default, anywhere from 72 to 600). These are standard file types, but printers’ software differs, so run a test file through yours before you take orders. Download one file, a zip per item, or a zip of the whole order from the Orders page in your dashboard. There’s nothing to resize or re-place.
Can customers who order by email, phone or at the counter use it?
Yes, with Kastomise Hosted: a shop on it doesn’t need an online store at all. Send the customer the page’s link in an email or a message, or open it on a tablet at your counter. They design, check the finished design and save it, and get a design code to give you. Look the code up in your dashboard under Orders, add the order reference and the customer’s details, and download the print files. Each shop takes orders one way, chosen in its Settings: through the Shopify widget or through Kastomise Hosted links. A shop connected to Shopify has no hosted page, so its customers design on your Shopify product pages instead.
Can I make a print file again?
Yes, for a paid Shopify order, while it keeps the shopper’s original photos (90 days). On the order’s page, “Make this file again” remakes a print file either exactly as it was printed or with the product setup’s print settings as they are now, for example when your printer asks for another format or a bleed. Earlier versions stay on the order, so you can switch back. Each file can be made again up to 5 times.
Can Kastomise send orders and print files to my own system?
Yes, in two ways. Webhooks: add up to 3 HTTPS endpoints in your dashboard’s Settings, and Kastomise sends each one a signed event when an order’s or a hosted design’s print files are ready, with links to the files and what the shopper chose. The API: make a key in Settings to list orders and hosted designs, download their print files and mark them printed from your own software. Both are documented for developers, and neither needs a sign-in to read.
