Printing Press Accessories: Litho Press Plate Backers

Aluminum Plate Backer

Precision Aluminum Plate Backer

Takach Plate Backers are precision ground on both sides for ultimate flatness. Made of 1" thick aluminum these relativly lightweight plate backers will not warp or emboss. A phenolic-resin sheet is bonded to one side, providing a durable work surface that will prevent scratching and is easy to clean. If the printer prefers, he or she may turn the backer over and use the bare aluminum surface as the top side of the backer.

Purpose of Plate Backer

Plate backers are required when printing ball grained aluminum plate, photolitho plate, polyester plate, on a litho press.

Hard Level Surface

A plate backer must provide a hard level surface, larger than the plate to be printed, and thick enough that the press will make contact when printing thin litho plates.

Aluminum is the Ideal Plate Backer Material

Backers made of materials other than aluminum, are not ideal.
Weight - The backer must be a managable weight that can be transfered onto and off of the press bed, aluminum plate backers are lightweight compared to steel or large litho stones.
Warping - Other plate backer materials especially plastics are effected by heat and humidity and will warp creating uneven printing pressure areas.
Durability - Plastic backers have the reputation for becoming embossed by the printing pressure. Slate plate backers have a tendousy to flake off.
These extremely durable Aluminum Plate Backers are ideal for printing litho plate as they will not emboss after repeated printing, are not effected by heat or humidity, and are light weight.
