🎨 How to prepare a print design?

In the Attachments tab you will find a box grid in PDF format. You can download it and apply your own graphic design to it. Below are a few key tips:

• 🖼️ File format: we recommend vector files (AI, EPS, PDF).
• 🎨 Color mode: CMYK, so the colors match reality during printing.
• 🖊️ Resolution: for raster elements we recommend 300 dpi.
• ✂️ Bleeds and safety margins: maintain 2–3 mm bleed and 5 mm margin from the cut and score lines.
• 🔤 Texts in curves: all fonts should be converted to curves (Outlines).

After preparing the project, send it to us by email at info@boxmarket.eu (mentioning the order number in the subject) or use file transfer services (e.g. WeTransfer, Dropbox). We will then start implementing your individual packaging!

Don't have your own project? 📝 No problem - contact us and our graphic designer will create a visualization and project for you at a price of 99 PLN net.
