PDF is usually the safest starting point

When the document is ready, export it to PDF. This reduces the risk of fonts, spacing or page breaks changing on another computer.

Check the page size

A4 and A3 are not the same as “almost A4”. If the design has a defined size, keep it rather than relying on automatic scaling.

Items that will be trimmed need extra artwork outside the cut line. Text and important elements should not sit directly on the edge.

Scroll through every page and check blanks, order and orientation. One minute here can prevent an entire incorrect set.

For unusual files, email druk@7minut.pl or show the file at the point. It is better to agree the parameters before printing.
