Free Format:
Free Format stamps are perforated with a line perforation machine; each perforation step produces one continuous line of perforation holes. This means that the sheet has to be perforated separately in both horizontal and vertical orientation. As an ideal stamp should have precise corner holes, we have optimized our technique to avoid "odd crossings" as far as possible.
This stamp type is recommended in all cases where the image format does not fit into the 2:1 layout of fixed format stamps, or if the required size is smaller or larger than the one provided by that format.
Free Format properties:
- High quality, medium sized perforation (11.5 perforation holes / 2cm)
- Number of stamps depends on stamp size, from one to more than 40 per sheet - calculate with a printable area of 17 by 22 cm on each sheet.
The stamp size is usually determined by jpg image size - we print with 600 dpi, i.e. an image with 600 by 600 pixel will result in a stamp image of 1" by 1" - with 2mm perforation borders on each side, the stamp size will be 29mm by 29mm (1.2" by 1.2"). There may be small deviations from this in order to fit into the perforation grid.
Of course, you can tell us the stamp size you require. We will adjust the image printing size accordingly and give you feedback if the resolution is too low. We usually calculate based on the stamp image size, not including the perforated border.
Example 4: Sheet with mixed stamp images (MI), information line (IL) and border texts (BT)
Example 5: Sheet with mixed stamp sizes (MX). Stamps may have varying sizes both vertically and horizontally, as long they fit into an rectangular grid (i.e. continuous perforation lines).
Example 6: Miniature sheet (MS) containing one stamp.
Example 7: Triangular stamp as pair and as single stamp (TR)
