subject: Intro To Black & White Printing Black Contact Paper Types [print this page] Black contact paper Those of you, things are done in Black contact paper of the process at any stage of life you want to select an appropriate role for her work. In the diving procedures are less possibilities of digital photography requires a good understanding of society. But worth the principles of Black contact paper is still the same as knowing a century ago and to choose wisely need.
There are fewer Black contact paper on the market today and become more expensive than a niche for the production of high quality documents even lower. So in that sense to find a card that you know, next year will be available.
There are two main types of Black contact paper in the current market situation and can be described as fiber and resin coating.
A) FIBER Black contact paper
If you look at the documents that the fiber several features that should be considered is:
First Base Black contact paper
The base Black contact paper for photo paper are used to clean extraordinary. Based photo paper is manufactured in factories, with special care to ensure their purity.
Black contact paper
Before emulsion coating, the base usually with a mixture of gelatin and a white pigment is known barium (barium sulphate) covered. The goal is to give an emulsion of pure white to ensure maximum cooling. Barite is chosen because it is purely a white pigment and is very insoluble and no adverse effects on the Black contact paper.
Second Dye Black contact paper
The color or tone of the document can be white or various shades of cream. In the documents of cream in general tend to give an impression of heat. base white can be simulated with the freshness and sweetness.

B) resin (RC)
Most modern newspapers Black contact paper are not coated with barium sulfate, but it is coated on both sides with a layer of polyethylene and is known as PE or RC paper. This coating is resistant to water, which prevents the bottom of the water-absorbent Black contact paper and chemical processing. The result is significantly lower than washing and drying times than that of coated barite required.
Who a quick profit or loss, and was about to sacrifice the quality to do so, documents in RC in general. These materials require much less time than the transformation of its report, the fiber. They require less attention to the balance of chemical fibers. These documents are used by nature to a lot easier than glass fiber.
Those who are of excellent quality and maintenance of general elections Fiber RC paper want. Costs consume more fiber and more difficult and time consumption, but produced by far the best version of a photo.
Black contact paper fiber is the choice of card printer creative, with experience in black and white that you want the best performance of the card. This document aims to provide a better quality finished product that the coating resin.
