rubber roller is made of nitrile rubber,sbr rubber,epdm rubber,neoprene rubber,plastisizers,softeners,crosslinkers,activators,and accelrators etc ..depending on the qualities needed these are the basic raw materials
some specially formulated chemicals are also needed which are the basic secrets of rubber roller manufacturers
the basic need for the rubber roller for printing purpose is swelling,crack,heat resistant rubber rollers
visit my site at www.phoenixrollers.infor the basic problems in printing rubber rollers running faced by printerswe need the best nitril rubber formulation
we need the best nitril rubber formulation
There are many formulations of rubber, so it depends on which formulation of rubber you use. Pharmaceutical rubber stoppers are made of Butyl rubber which is unaffected by alcohol.
Rubber cement is a type of glue. It is made from elastic polymers such as latex that are then mixed in a acetone solution.
Offset printing or web offset printing is a commonly used printing technique in which the inked image is transferred, offset. This is done from a plate to a rubber blanket, then to the printing surface.

Cloth, sponge rubber, metal, wood, plastic, etc.
Rubber wheels provide a more comfortable ride since they absorb some of the vibration from the surface. They also provide more grip.
It is an indirect printing method, hence the term offset. The image is first transferred from the metal plate to a rubber blanket, and then from there to the printing surface. It is one of the better printing methods and fairly cost effective.Offset printing was discovered by accident. They were using a rotary lithographic press and forgot to load it. When the operator loaded it next, he realized the resulting image was clearer when printed from the roller side.For smaller jobs, digital offset may be more cost effective, since you don't have the preparation costs, but it is a more expensive method for larger number of copies than standard offset printing. Rotogravure or photogravure gives slightly better quality than offset, but those are not cost effective until you get into hundreds of thousands of copies.
YEAH i got 22 inch wheels on my 2001 DTS but you gotta get either 22x7.5,22x8 or 22x8.5 max with a +38 - +42 offset. rubber has to be 30 series too (RUBBER BANDS)!
Newspaper printing used to work by pressing a page of paper directly onto a block of type. This used to be called a Linotype typesetting machine. Today, however, offset printing presses are used. The image to be printed is etched onto a thin aluminum plate. The plate transfers its inked image onto a rubber roller which then gently rolls the inked image onto the page.
