Sign making processSignage plate determines the quality of signs, and sign making process, determines the quality of the production of signs. In the production process, in strict accordance with the relevant standards need three processes to execute, we can guarantee
Certificate good quality signage products.1, the bottom plate production. Signs, text, graphics and typesetting plate they use a photographic plate, the first system out of a single piece of the original, and then even the sun drying machine even imposition. Imposition respectively when taken according to the requirements of precision parts
Imposition and with no spacing spaced imposition. Signs size less demanding, can be no imposition pitch. After printing, cut or cut directly after stamping. Signs that require high dimensional accuracy, should
Using spaced make-up, after the printing is completed by the positioning hole punch press molding position, the distance between each of the parts may be 2mm, 2mm hole for positioning aperture spacing 4mm, the whole area may be
400 × 400mm, or according to the process set design. If color printing signs two-color or two or more colors, photographic negatives rules should be positioning line, positioning holes can be painted on a photographic plate negatives main pattern
In order to ensure the accuracy of the positioning of the punching.2, silk screen positioning. Positioning is the key to accuracy, positioning accuracy is the key to determine the quality of the metal printing plate. Custom screen printing plate on the plate, is to ensure that the graphics are printed on the same workpiece
The exact position of the surface, uniform color overlay accuracy and meet the requirements of process means. According to substrate materials, different, screen printing plate positioning method also all have different body, commonly used are the following
:The first is sidelined positioning. It applies to straight edge artifacts, such as: nameplates, panels, all kinds of disk, etc., at the time of printing the article can be positioned close to the two right-angle side of the workpiece.The second is chrome positioning. Suitable for printing shaped molding of the workpiece, the workpiece can be molding blanking the frame, after trimming the gap, according to step aside positioning method, the frame needs to adhere to the position on the platform
When printing simply shaped workpieces blanking frame can be placed.The third is the hole location. Hole positioning graphic make-up applied to the same screen, that is, first on the plate out of the positioning hole to hole location when printing, still positioning the final hole of the workpiece blanking die molding.The fourth is coincident positioning. Suitable for screen printing chromatic graph on the transparent material. The second color pattern can be silk printed on cardboard and covered with a thin film printed with the first color pattern positioning, so that the same two-color pattern
Bit packages meet the design requirements of size, and then printed the first color film and internet cement chart when printing a second color pattern simply printed on a transparent workpiece and the platform of the first color pattern of the first color pattern
Overlap, you can achieve the purpose of positioning.3, metal printing plate ink formulation. Metal plate with silk screen printing ink demand is strong adhesion, good wear resistance after printing graphics clear, fast drying and without censorship. A metal plate screen printing oil
As is the use of alkyd, phenolic and other synthetic resin as binders, adding some pigments, additives made of special ink. Preferably this ink printability, and air-dried at 120 ℃ print conditions
Bake 2 hours to dry. Its bright surface of the ink film, three-dimensional, with excellent adhesion and wear resistance of the aluminum plate. This ink ink film with JM-l-type abrasion tester to test the film, 7509's Load
Rubber wheel grinding pressure up to 500 times with a cloth round grinding up to 5000 times.If the screen color signs, reference may be colored with ink printing ink color samples related transfer ink should add the right amount of varnish and desiccant. Ink drying agent added is about 5 to 8% of the total ink, plus less
Easy to dry, plus much more affected the adhesion of the inks.4, the quality of the metal printing plate requirements. Signs silk screen text, scale, graphics, and color should be consistent with the positioning hole drawings, finished surface should be no scratches, stain adhesion, ink film should
Meet the requirements.
