Some categories in the format tab have the item "any size or custom". This selection causes additional fields to be displayed.
The size defines the dimensions of the finished product, which is made of a larger printing sheet. After entering any size, e.g. a self-adhesive sticker, the system will estimate the amount of use on a given size located on the printing plate, which often results in unusual expenditure to choose from as 4211, 121, etc. which are automatically calculated from the division of the sheet.
For ease of use, in some categories a list of the most popular sizes defined is prepared.
