Stamps Are Only as Good as the Rubber and Inks

Think of the stamp as a hand operated printing machine. It does have limited functionality in that it can print only what words or design is there in the rubber. However, it is so cheap to make that you can order dozen or more stamps Sydney based manufacturer offers and use the one to suit your purpose. Stamps look alike but can be different in many ways and all these factors contribute to quality of impression. 

The Rubber
Rubber is a generic term. Within this you have many different types of rubber such as silicone, polyurethane, EPDM, plain old vulcanised rubber and neoprene to mention just a few types. Not all types are used in rubber stamps. Vulcanised rubber is the most commonly used type but it is prone to degradation due to ageing and effect of ink that is used in rubber stamps. When you buy stamps Sydney based supplier offers from the likes of Colop and Trodat you are assured of better quality rubber. Apart from ageing and degradation what these manufacturers also consider is the ink take up ability. Ink must adhere uniformly to the surface to create an even impression. 

Ink
The ink also makes a difference to the impression rubber stamps create. Inks may be water based or solvent based and may have dyes or pigments along with additives. Quality inks have properties that adhere to the rubber surface evenly and do not cause blotches when printed on paper. When you source stamps Sydney based supplier offers you can also get matching high quality inks in different colours. 

Technologies
Rubber stamps may be made by photo polymer process, by the process of vulcanisation or modern laser cutting technology. The last one is better in giving sharp and clear outlines even for small font sizes. The better manufacturers use quality rubber sheets that are then cut and engraved with lasers to create the stamps. 

Stamp users may not delve deeper into material of the stamp or how it is made or the ink. However, if you know more about these things you will appreciate how important they are and why top manufacturers use carefully chosen materials and processes so that the stamp delivers the perfect impression. 

Non-standard ink
Take the common wooden handled rubber stamp. You use it with a stamp pad containing water based or solvent based ink. Can you use other inks to print on metal or cloth or plastics? It is possible provided you can get inks in small quantities for your purpose. There are times when you may wish to use the stamp on metal container. In that case get a tube of printing ink used by metal printers and spread some on a flat plate. Press the rubber stamp on it and then transfer the impression to the metal tin. Of course, the normal rubber stamp supplier will not stock these types of inks for metal and plastics printing but this is mentioned just to show how versatile the stamp is and how you can change inks and use the stamp to print on even polythene bags and metal foils.
