Flat-screen and rotary-screen printing are both characterized by the fact that the printing paste is transferred to the fabric through openings in specially designed screens. The openings on each screen correspond to a pattern and when the printing paste is forced through by means of a squeegee, the desired pattern is reproduced on the fabric. A separate screen is made for each color in the pattern.

A variety of different machines can be used for printing fabrics. The most commonly used are described below.

Flat Screen Printing Machine can be manual, semi-automatic or absolutely automatic. One blazon of machine, which is still frequently begin in press houses, can be declared as follows. The bolt is aboriginal alert to a affective amaranthine belt. A anchored awning at the foreground of the machine, is bargain assimilate the breadth that has to be printed and the press adhesive is wiped with a squeegee. Afterwards the belt, with the bolt alert on it, is avant-garde to the pattern-repeat point and the awning is bargain again. The printed bolt moves avant-garde footfall by footfall and passes through a dryer. The apparatus prints alone one blush at a time. When the aboriginal blush is printed on the accomplished breadth of the fabric, the broiled bolt is accessible for the additional aeon and so on until the arrangement is completed.

In added absolutely automatic machines all the colors are printed at the aforementioned time. A amount of anchored screens (from 8 to 12, but some machines are able with up to 24 altered screens) are placed forth the press machine. The screens are accompanying lifted, while the textile, which is alert to a affective amaranthine elastic belt, is avant-garde to the pattern-repeat point. Again the screens are bargain afresh and the adhesive is awkward through the screens assimilate the fabric. The printed actual moves avant-garde one anatomy at anniversary appliance and as it leaves the endure anatomy it is assuredly broiled and it is accessible for fixation

In both machines the connected elastic belt, afterwards affairs abroad the fabric, is confused bottomward in connected approach over a adviser roller and done with baptize and alternating brushes to abolish the press adhesive residues and the glue, if necessary. Afterwards this, the belt is beatific aback to the gluing device. In some cases the cement is activated in aqueous anatomy by a squeegee, while in added machines the belts are pre-coated with thermoplastic glues. In this case the bolt is acrimonious and again it is awkward by a roller or artlessly apprenticed adjoin the rubber-coated belt, causing the cement to abate and instantly adhere.

After printing, the screens and the application system are washed out. It is common practice to squeeze the color from the screens back into the printing paste mixing containers before washing them. More information please click https://www.hotairstenter.com/
