In detail

DTF Mygrafistas sells DTF transfers to brands, print shops and resellers across Europe. At its heart is a custom gang sheet builder we wrote from scratch as a WordPress plugin, along with a European VAT plugin and a desktop production app.

Custom gang sheet builder

Customers upload as many designs as they want, set size and quantity or pick a preset (neck label, hat, pocket, front, bag, back). The builder lays them out automatically on the 570 mm roll with a 5 mm gap, rotates them where needed and shows length, price per meter and total live, highlighting the tier the customer reaches.

The builder with 4 designs: the 'Your price' tier activates automatically

Automatic layout (nesting) on the 57 cm roll

Automatic trimming of empty space around each PNG, so the size the customer enters is the size of the design.
Resolution (DPI) detection with a low-quality warning.
A 4-step guide and a guided tour inside the builder.

Any file, ready to print

If the customer uploads a JPG, WebP, SVG or PDF, an in-browser converter (with pdf.js) converts it and removes the background. There is a tolerance slider and a checkerboard preview. Files without transparency get a warning.

The converter steps in when the file isn't a print-ready PNG

The right price, the right VAT

The price is recalculated on the server at checkout, with a 1 meter minimum. Long sheets are split into equal pieces of about 3 meters.
European VAT: a business option, VAT number check in VIES, 0% with reverse charge for businesses outside Greece, and a new check when the shipping country changes.
Real-time FedEx shipping rates.

Customers who come back

“My files”: a library of each customer’s designs, ready to reorder, with saved carts and emails before files are deleted.
Marketing engine: abandoned carts, popups, exit intent and a “Scratch & Win” welcome offer. It later became our own ERP Marketing plugin.
6 languages (English, Greek, German, Italian, Spanish, Swedish), with the first visit opening in the language of the visitor’s country.
A review filter and a page with a video order guide.

Production with no downloads

In the admin, orders move through a drag & drop pipeline. For printing we wrote a Python desktop app that reads the order ZIP and builds the 300 DPI print file locally. That way a ~100 MB file for an 11-meter sheet never has to be downloaded from the server, and designs under 150 DPI are flagged.
