Focus on screen printing for acrylic nameplate

Acrylic nameplate in the process, often need to screen printing, screen printing in the acrylic nameplate production process is very important, we need to pay attention to what issues below for details Note acrylic processing screen printing.
1.The import sensitive adhesive fine stencil making, we must choose the high resolving power and high tension, low elongation import mesh. Japan Murakami production of SBQ the single fluid sensitive glue NBC Mesh and other brand-name products, although the price is more expensive than domestic, but produced clear screen graphic neat edge, but also to ensure a multicolor overprint or four-color network printing position accuracy. Such as the text is too small, the line is very thin, can be a 350 mesh screen, the same time, it should be equipped with grinding smooth the imported ink or light-curable inks.
2. color screen printing, generally by virtue of the experience of printers for each batch utilize Mesh, photographic film thickness is not the same, often caused by the color cast of the printed product, "barrels of ink color is not prospective, see real Yan "after the scraping of the last version of the truth is. Therefore, each batch of live test India with Shaizhi good Screen shot samples, customer confirmation consistent with the original color, in order to enter the formal printing.
3. large-format painting must screen printing machine printing, small format available inhale ink pad printing. Printing process, should remain the six consistent with: a multicolor screen mesh distance should be consistent; b squeegee speed consistent; c squeegee pressure consistent; the d ink viscosity consistent; e. Manually size blade squeegee hardness consistent; f. temperature and humidity of the pressroom consistent.
4. Sided organic board signs should be used in a transparent plate, the use of anti-Indian, to be graphic printing is completed, and then cover the printed layer of background, the adhesive must use screen printing glue between the two poles. Typically with 80 to 100 mesh, nylon mesh, waterborne photosensitive plastic production network version can be side printing can also be printed on both sides, until the screen printing plastic color translucent (about 20 ~~ 30min) both sides aligned bonding together. Bond line is not subject to the influence of the mechanical polishing.
5. Multicolor overprint, in order to ensure the accuracy of overlay guaranteed Graphic Version size is the same premise, can be the size of the other version of the appropriate scaling (scaling dimensions shall not exceed 0.1 to 0.2mm). When printing, deep pressure light version, the graphical version compressed put Edition, so that when organic crop are not allowed to board or manually put the plate positioning block convergence adverse overlay accuracy.
6. the printing ink should be used in high gloss, abrasion acrylic inks, especially not in the surface printing use matte ink, because the ink is not rubbing, color is not bright. For outdoor light box signs, you should also use the imported good lightfastness ink, resistant to strong light, extending its life.
7. Proofing film can not use a laser printout or sulfuric acid paper is issued instead, must be professional factory output the Zhengyang or anti-male film, each output to output a blank with positioning crosshair film. Plate burning, the the first blank crosshairs film with a transparent adhesive tape on the glass, the other colors of the film should take this as the basis, so sun screen position in order to be consistent.

8. Acrylic size cut to be consistent, the two adjacent sides of a 90 ° angle and thickness uniformity. According to the the printed screen size, appropriate aside margin to be printed after cutting the excess amount of edge. Multicolor overprint or four-color printing, magnetic white or transparent organic board should be used. Magnetic whiteboard used for positive print, the transparent plate for verso printing. Sand panel is not ready own plate, with a plain glass plate sand surface ink printed indoor display, matte signage
9. often a lot of static electricity and dust, dust the surface of organic films such as adhesion on the screen will cause the text blocks of color incomplete, appear scrap. Therefore, the printing must be conducted in a clean and dust-free room. Surface dust can be divided into two steps removed first with a damp cotton cloth to wipe off the dust on the surface, then brush with electrostatic dust or dust removal roller brush residual dust. Printing, side printed side check if the problem, the timely liquidation screen printing.
10. domestic large and medium-sized shopping centers products (cosmetics, jewelery, watches) advertising frame more than the pursuit of the matte effect, in order to set off the bright and colorful merchandise. Manufacturers of acrylic panels do not have this board, choice of plain glass plates or transparent plate ink printed directly on the sand surface treatment, you will be presented when the ink dries, sand sense of matte effect. (Note: There are matte surface acrylic, but the cost is relatively high. Another way is to paste the translucent glass film)
