Clear Stamps
Sellos que garantizan una buena impresión.
With manufacturing sites in the UK and the USA, we are the largest manufacturer of custom clear stamps in Europe and North America, world leaders delivering to all destinations worldwide.
Our core expertise is manufacturing photopolymer, packaging it in imagepac sachets and using them to make the highest quality, beautiful, clear photopolymer stamps.
Standard sizes
Our standard sizes are A4 (8”x12”), A5 (6”x8”), DL (3.5”x7”), A6 (4”x6”), P6 (4”x4”), A7 (3”x4”) and A8 (2”x3”). However, if you require a different size, we’ll do our best to accommodate you.
Our stamp sets are packed with a clear protective acetate sheet, a separate acetate sheet printed in black or colour ink with your design applied to the top.
We can insert a backing card printed in high resolution on quality card and insert them in a sealed clear bag with a hanging slot.

How we guarantee dimensional accuracy in your clear stamps
The process of making your stamps
Artwork to negative
Your artwork is created from your digital file, and this is transferred to a printer to create the negative and is an exact physical representation of it. It is accurate to the thou as we use the highest resolution large format printers on the market.
Negative to stamp
Light from the exposure beds hardens the photopolymer. All liquids shrink in the transition to solid (water being the only exception) and photopolymer shrinks by about 3% in volume as it polymerizes from liquid to solid.
In our process this takes place slowly and the liquid resin that surrounds the cured stamps replaces it. When the exposure is finished, the light through the negative will have hardened the liquid polymer to be an exact copy of the negative, and it is a dimensionally accurate representation.
How we test and prove this
We will run periodic test negatives through, one is a curved protractor measurement and the other a straight rule, covering both straight and curved accuracy. We make them into a stamp and then measure against the physical standard.
