High grade photopolymer
All our premium clear stamps are made from high grade photopolymer resin, not silicone, acrylic or rubber.
High clarity, shiny stamps, transparent for easy inking and positioning of stamped image.
Permanently clear stamps. We do not advise storage in sunlight as prolonged exposure to UV will weaken stamps.
Our premium clear stamps are tough and can be stretched and will relax back to their original shape.
Naturally sticky back
Premium clear stamps have an excellent back adhesion, allowing repositioning many times on an acrylic block. Storage on plastic keeps the stamp back sticky.
Our stamps are designed to work excellently with all water based inks which accounts for over 90% of all stamp ink use. They will also work excellently with solvent inks, prolonged use will eventually weaken the stamp. Use solvent cleaners sparingly.
Health and safety
Cured photopolymer stamps carry no health risk (we have not tested for FDA compliance or food compatibility). They contain no latex, phthalates, melamine, carcinogens or toxic or harmful compounds.
Using solvent inks with clear stampsYou may be aware that photopolymer stamps have been used in the printing industry for over 50 years and are meant to transfer ink which makes them ideal for stamp material. So what inks can be used with polymer stamps? Are some better than others? Although water based inks are generally recommended for use, solvent based inks can be used too.
Just bear in mind, polymer is like us in that it doesn’t like too much sunlight or too much alcohol. The solvent in Staz-on is the most aggressive on stamps of all the stamp pads and will attack the upper surface on contact. This gives the stamp more grab on the paper and makes it feel sticky when removed.
In reality, the solvent is only affecting the stamp whilst it's liquid, which is only for a few seconds before it evaporates and even then only the thinnest surface of the stamp. After repeated stamping this effect is reduced as the stamp becomes protected by a layer of pigment.
We use Staz-on internally with polymer stamps, and even with repeated use (stamping many times a minute) they last a long time!
Our recommendations for using solvent based inks with clear stamps
1. Use solvent based cleaners sparingly
When you use a solvent based cleaner it can be more harmful than any solvent based inks as inks tend to be dabbed on stamps whereas excessive amounts of cleaner may be applied in the belief that it will clean the polymer thoroughly. Also, cleaners tend to contain greater amounts of solvents than the ink which can degrade polymer over time. So you can use cleaners, but do it sparingly.
2. Create a film between the polymer and ink
Sometimes applying a lighter colour or clear ink before applying your StazOn ink will help create a film or barrier which means that the solvent based ink is not directly applied to the polymer.
3. Soapy water
If your clear stamps get dusty or dirty you can simply wash them with warm soap water and they will stick to your acrylic block again
