Stamping up with Polymer Rubber
Among the various ways for manufacturing rubber stamps, the polymer stamp making technique is the winner of all available stamp making methods for rubber stamp makers at home. Manufacturing polymer stamps will allow you to get professional quality custom rubber stamps at the lowest price possible!
It might surprise you that polymer stamp making is now the most common method of manufacturing stamps commercially today. The majority of business ink stamps, self inking personalized stamps and increasingly so craft stamps are now more often polymer stamps. Polymer stamps are also known as acrylic polymer, clear stamps, clear rubber stamps and rubber plastic stamps. Interestingly, polymer stamps contain no rubber at all and are still called rubber stamps!
Stamp Making Rules
Before you launch into making your own polymer rubber stamps, you must keep in mind three important factors about polymers. Pay attention to these and you can be assured of a high quality rubber stamp.
# Platemaking Polymers - Used extensively in the printing industry not all photopolymer plates will produce rubber stamps. To make a stamping die a polymer with the durometer reading of 40 is ideal; this is the hardness scale of the cured polymer. InstaPlate is just such a kind of polymer designed to make rubber stamp dies and best suited for home use. It is available as a photo polymer gel in a sachet (commonly known as ‘polymer in a bag’). With InstaPlate, you can be assured of a good quality polymer so request it when you investigate your stamp making supply.
# Polymer Solidification - Some stamp making kits employ other types of polymers that solidify under natural light or a single light bulb. This is not recommended as polymers that solidify under a specific UVA light range are always better. All professional stamp makers use polymers like InstaPlate as it allows control of the UVA light at a specific wavelength to make stamps. So invest in a quality UV exposure unit along with a commercial grade polymer such as InstaPlate to create stamps like the professionals do, this is especially important if you are interested in producing wholesale rubber stamps at home for resale.
# Strength of your Rubber Stamp - We often come across polymer stamps with no structural backing allowing the stamp to naturally stick to a mounting block. While these seem great, they are susceptible to tearing, dirtying and distortion. A strong permanent backing avoids these problems and is becoming very popular now that we have products such as EZMount and InstaGrip. InstaGrip is a new method of affixing rubber stamps to acrylic blocks and is a repositionable mounting system designed for mounting stamps onto acrylic. InstaGrip is basically a clear thin silicone repositionable mat that sticks both to the stamp backing and the acrylic block. Since it’s transparent, it will allow you to see through the stamp and the block to place your impression, making your stamping process easier than ever before.
The Light Source
You don’t need to spend a fortune on a light source for making stamps at home. Commercial stamp machines have built in timers that control the exposure of the polymer and are quite expensive. A better alternative for home stamp making is a smaller craft stamp maker that utilizes an external portable countdown timer. The UVA light output from one of these units will produce the same quality stamp as the larger commercial stamp making systems.
