Screen Printing In Simple To miss A couple of Problems
In the high quantity screen printing manufacturing course of, if a particular part of the viewer shouldn’t be aware that it will bring to the manufacturing of a collection of problems, but this case is just not resolved, would have been troubled manufacturing.
Here mainly on the production of simply neglected but typically encountered several issues discussed.
, Color screen Display screen colours are white, yellow, amber, red, of which the yellow wire is better. We used the production of Japan or Germany imported 270 ~ 280T of the yellow wire, the special fantastic print, we frequently imported 350T yellow display screen.
Why use the yellow wire it? We all know the eye-catching colors of nature are as a result of role of mild, no mild there isn’t a shade, mild colour is set by the frequency of light waves. Red, orange, yellow, inexperienced, blue, blue, purple is the visual nerve can feel the light, as visible gentle. Selective floor absorption and reflection of mild which have completely different colors, in short, we can see the colour of any color is light. That is, when a bunch of yellow mild publicity to the cute teacher shirts surface, only the yellow light is reflected, and stimulate our optic nerves and coloration, whereas others have been absorbed shade, so we see the item color is yellow.
As screen printing within the printing down the publicity, the use of the ultraviolet light, violet gentle is the shade of the blue and magenta hue of the mixture of two reflected light, that is lacking in the dead of night yellow hue. The exposure, the purple on superposition of the yellow wire plus black, so the yellow wire on the floor (that’s, the bottom emulsion layer) is just not delicate or less exposed, so no “back sun” phenomenon, high-definition photographs obtained , doesn’t produce vignetting. What is again
solar? That when the light by way of the clear a part of the film emulsion layer to achieve, within the coating layer within the center or backside floor of the white screen of reflection, refraction, and the phenomena of sluggish fireplace, just from the bottom and the inside coated floor publicity This phenomenon is named “again solar.” It is going to create digital halo trigger publicity affect colour reproduction.
II emulsion coating Will probably be ready from photosensitive liquid into the stainless steel tank, light-delicate liquid about half the tank. Coating slot and tilt the display screen at the underside contact, while tilting the tank out of photosensitive liquid, whereas the tank slowly and evenly put up along the display surface to coating. Coating velocity cannot be too quick, too fast will cause foaming emulsion, the membrane surface will outcome pinhole; too gradual will trigger uneven coating emulsion. In order to obtain one of the best coating outcomes, one of the best start printing contact with the substrate aspect to coating, coating area must be slightly smaller than the display body after which coated screen upside down as soon as once more, and finally Screen unfavorable drying after coating so that the mesh stuffed with photographic emulsion. 30 ~ 35 utilizing scorching air drying is the very best, this can scale back the drying time. If the temperature is greater than 40 , the display screen will produce a thermal fog phenomenon.
Emulsion in the liquid phase of low sensitivity, sensitivity with the increase of dry coating film is completely dry to achieve the required sensitivity, it should be fully dried earlier than printing down, and so quickly after drying complete burn out.
Course, the manufacturing scenario of each manufacturer is completely different from the coating technique and frequency was also completely different. Coating technique used in our factory is a spot that after coated the positive and detrimental three times, and then focus on drying.
Page loading because the mud will produce pinhole screen, so to maintain the room clean. At the same time to deal with unhealthy display display surface will end in too many needle sticks. Emulsion coating, dry place too shiny, the display will produce a full page image of the hair spray, affect print clarity and saturation.
Screen Printing manufacturing unit is mainly producing family ceramics decal, the principle export products, domestic merchandise complement. Exported to the United States, Britain, Canada and other countries of the 20 packages tableware, bowl, and cook pasta dish, grow to be people favor.
3, plate burning, trim
Plate burning, ought to first test the photographic film unit surface and the surface of the glass plate burning models have soiled or dust is best to wipe clean with a cotton dipped in alcohol before work. The floor of silver halide film has connected cute teacher shirts to optimistic movie Kitt shiny side is negative. Printing down, should the membrane surface and the movie model of the emulsion floor dense community of fit, leaving strains exposed seams. Photographic publicity time must be based mostly on the type of thorns, photosensitive film coating thickness and actual extent of the black solar picture and printing request. Photographic film coated with thicker layers, you want an extended exposure time corresponding to complete solidification film model. If the sun image on the true extent of graphic black enough, namely a gray instead of black, it should shorten the publicity time, with a corresponding extension of growth time, so that part is not fully transparent photographic illustrations.
