What is the difference between imagepac Stampmaker stamps and shop-bought clear or rubber stamps?

Color: Standard rubber stamps are always colored and opaque. Silicone or acrylic stamps are clear. Polymer is naturally clear, we color stampmaker polymer red to make it easy to see the image, whilst it is still transparent for easy positioning.

Polymer stamps are normally made with a base formed during a primary exposure, then a second exposure make the image. We wanted stampmaker to be the easiest ever way to make a stamp so we designed it so that a single exposure is all that is required. This means that stampmaker stamps always have lovely deep etching. However, they do not have a sticky back so you need to use imagetac tape to mount them.

Image Quality: Standard rubber can hold a lot of detail whilst silicone or acrylic stamps usually just have simple designs. Polymer can hold the finest images possible and make the most intricate stamps, even photographs.

Ink usage: Rubber based stamps can be used with any inks; polymer stamps however, are designed for use with water based inks. Long term use of solvent based inks and cleaners with polymer stamps will cause them to curl and weaken. Having said this, you can easily get a long life out of a polymer stamp when using solvent based inks by just cleaning soon after use. Note: Do not overuse solvent cleaner, it can damage polymer stamps if used excessively.
 
 
What inks can I use with my stamp?
All photopolymer stamps work well with pigment and dye based inks (water based inks). You can use solvent inks, but bear in mind that the solvent (including your stamp cleaner) will degrade your stamp over time. Use solvent cleaner sparingly.
 
 
What material is the imagepac?
Imagepac is a photopolymer resin. Photopolymer has been used in the printing industry for over 40 years and is used today to make printing plates. It is well known for its imaging ability and its ink transferring ability.
 
 
Is it toxic or harmful?
No. Photopolymer is a mild irritant. If you get it on your skin, wash with warm soapy water. When hardened it is completely safe to handle just like any other clear stamp.
 
 
Can I make my stamp completely clear?
No, imagepac Stampmaker stamps will have a residual color but if you leave them a minute or so longer in the post exposure they will get lighter.
 
 
Can I make my stamp less tacky?
Yes, leave it under the lights in the water for a few more minutes, but expect the red color to fade. Have the water just covering the stamp.
 
 
Can imagepac be hardened in normal light?
It will be fine in a normally lit room for many minutes, but will harden quickly in sunlight, store unused polymer in a closed box.
 
 
What is the light in the Stampmaker?
It is mainly UVA peak 360nm, you should avoid direct contact with the eyes.
 
 
Why is my stamp not washed out properly?
To wash your stamp out, you should hold it under a gently running warm tap until the liquid has fallen off, then squirt a generous amount of washing up liquid (dish soap) on it and rub it in a circular motion with the brush until it is clean. Finally, rinse and check against the light to ensure you have removed all liquid polymer.
 
 
Can I use soap instead of detergent?
Yes, we recommend dish soap, as it is quicker and better.
 
 
What happens if leave the imagepac in the water too long?
If left in the water for a long time the plate will turn white and will swell up, this may permanently deform the plate (probably after about 1 hour).
 
 
Can I use cold water?
Yes, but it will wash out faster and easier in hot water.
