How is wallpaper produced ?

Starting point is a strap material to be printed. Without special wallpapers (glass fabric-, for metal-, for grass-, for cork-, for textile and other wallpapers), wallpapers were produced on either paper or non-woven base. At this materials put concretely are dependent on the quality the respective one end product. We would like to introduce the discrete production methods to you without wanting to lift up a claim of completeness with that in the following. This simply is due to this, that exist in the wallpaper area no clear concept standards and the name of the wallpapers be subject to the current fashion partly.

Collotype is the original machine printing process (more than 100 years old) which has taken the block print off collotype wallpapers. Wallpapers could be produced more effectively and were payable also for the normal consumer with that. The printing process got his name by the binder (glue - glue pressure) used in the colour. Originally, wallpapers were produced with up to 12 colours on a ligneous paper in these so-called high printing process (the printing areas stand more highly than the pressure top-hat). These wallpapers didn't have any protective cover in the past so that they weren't smudge-proof. You will only find collotype wallpapers rare today because the production method is expensive. Nevertheless these wallpapers have her own charm on for since one still recognizes a certain degree of trade and exclusiveness by them. The quality with a mostly washable surface is no longer comparable with the original collotype. It is a high value product which is produced also on non-woven base.

Today, the base technology almost only becomes rotogravure wallpapers as a rotogravure described for the pressure of wallpapers and borders. Today, pure rotogravure wallpapers are hardly produced. How the name already says is at the rotogravure the colour in ink cells which is transferred to the paper or non-woven length with help of a counter-platen (impression roller). Common depression printing presses have publications which are equivalent to the number of the colours up to 6. This number is completely sufficient for the design since shades of (brightness control) about the form of the ink cells steered and secondary colours reached by superposed printing.

The silk-screen print is a printing process at which the coloured printing ink is printed by a sieve printing form with a scraper on the strap material. In comparison with the other printing process the pressure speed is relatively low. The silk-screen print is described as porous printing, because the printing places of the sieve printing form are colour permeable. The silk-screen print true for historically seen as a fourth print method. Preferential valid the silk-screen print is used for the production of blown vinyl wallpapers.

The ambossing wallpaper is a wallpaper way at which a wood-free paper is printed in the rotogravure first. After this, this printed strip of wallpaper is concealed, embossed and then dried in the wet condition with a second woody paper web. Through this the wallpaper keeps largely her three-dimensional form. There also are production methods at which the wood-free top length is characterized first and then concealed with the back length. Through this the back of this ambossing wallpaper is slippery.

Like as when the ambossing wallpaper get this wallpaper produced in two production steps. The colouration is in the first step (e.g. rotogravure) and the acrylic order carried out for the second step at this. The applied acrylic is then on foamed in a dry channel. Advantage of this wallpaper manner is his good environmental compatibility since the acrylic is on foamed physically. Acrylic foam wallpaper is sold in different "varieties". There is the velour wallpaper next to the normal acrylic wallpaper and also at the so-called structure wallpapers one will find some hard foam wallpapers which are produced the above mentioned method in which, however, the foam structure was changed a little to obtain the desired qualities.

Pasta made of polyvinyl whose propellants are moved back (plastisols) are applied on the paper or non-woven length and led by a heat tunnel in the sieve printing process mostly. The foam can be pressed and smoothed after cooling off. In the depression printing process the base material is printed and cooled into the vinyl pattern or structures ambossed and following partly in the hot stamping plant deeply. Partial micas and quartz granules are used for the visual surface embellishment today. Flat vinyl wallpapers are rubbing constant, the ambossment are absolutely stable.

Sisal wallpapers isn't an own wallpaper manner in the technological meaning. Sisal wallpaper is a special way of non-woven wallpaper at which sisal fibres (plant fibres of the agave) were earned to into a non-woven bed or found on it. One obtains a unique stability of this natural product with that. Sisal wallpaper can be produced in different printing process (most collotype or silk-screen print). This wallpaper could become the new favourite for architects on reason of his excellent material qualities.
