First, screen printing machine screen frame

Generally there are two kinds of wooden frame and aluminum frame: the price of wooden frame is cheaper, the packaging is safe, suitable for manual printing, but the recycling is relatively poor, because the net pulled out of the wooden frame is easy to relax, reduce the recycling of the net, the price is a few dollars, aluminum frame relative to the wooden frame has its effect of reaching a high recovery rate, not described here!

Second, silk screen gauze

There are many kinds, like nylon gauze, tapecord gauze, metal gauze and other wine packaging, from the cost and applicability of consideration, generally use nylon gauze, in addition, there can be a difference in color, for dyed gauze, this is relative to the combination of four colors printing, because dyed gauze can be Mohr phenomenon, this is later to say, here do not say, This remember said before the mesh mesh number, I said "T" is only the mesh model electronic supervision code, mesh number of the expression method should be mesh/square meter, generally 77T=180 mesh 100T=250 mesh 120T=300 mesh 140T=400 mesh 165TT, I do not remember, do not know whether, please correct the combination printing, In addition, there are 43 tons of mesh. 34T. There are other models!

Third, pull the net

There are manual, mechanical, pneumatic mesh, for the general screen printing processing plant, the requirements are generally not too high printing suitability, the first two can be completely solved, for the latter kind of mesh machine, I have not used, only seen in books! Net pulling, that is, put the net frame on the bracket of the net pulling machine, and then wipe on the strong net pulling glue, and then put the net yarn on the top, solid, and then pull hard on all four sides, you can use the dynamometer to measure whether the four sides of the force is the same color, to have a certain amount of strength, then make the net frame on the top, and then wipe the glue on the surface, so that the net yarn is tightly bonded, and so on. There is also for the wooden frame, you can use nails to go up, the principle is similar.

Four, wash the net

Washing network generally with special washing network chemicals, but very troublesome people, until those oil pollution removal, has spent a lot of time, the general processing plant, speaking of time, will not go to typesetting, I talk about a very effective method here, is to use washing powder, of course, is to remove the stain strong kind, Tide, or other brands of HP, it is up to you. Heh! Wetting the screen board, in addition, is polished with cotton cloth, which has another advantage, is conducive to the adhesion of the photosensitive paste. Saves one step of polishing. Remember to polish both sides, and for the front packaging decoration, when polishing, the force must be light to avoid the loss of the mesh. Dry in the dryer and set aside.

Five, on the photosensitive paste

Before speaking, it is necessary to talk about the photosensitive paste digital printing machine, the preparation of the photosensitive paste is not said, or the purchase from the market is more guaranteed, of course, there are domestic and imported, in my previous use is all imported goods, Italy's photosensitive paste is good wine packaging, as' such as gauze, Swiss gauze more than Japan and Germany's gauze, of course, this is my one-sided word, That's up to you. The photosensitive paste on the market requires its own call, you can use hot water to moisten the photosensitive powder first, and then pour it into the photosensitive paste to fully adjust it, and use it after a few hours. Large factories have automatic sizing machine, the thickness is very uniform, small factories can be their own sizing, can be completed by the plate maker!

Is to paste film film, that is, soft film three-dimensional printing, this is relatively simple, that is, compared with the so-called photosensitive paste, indirect and direct method, (do not understand the front) you only need to wet the film, paste to the place you need to feed the paper, and then use the sizing vessel, gently press, so that the film is inserted into the mesh, dry the water, and put the baking machine.

Six, bake screen printing plate

The baking screen plate is carried out in the baking machine, the temperature is generally baked at a temperature of about 30 degrees, if there are many times the sizing process, there will be many times the baking, note that the baking screen must be dried EFI, otherwise you must know the consequences. For the thickness is mainly to see the substrate, different substrates have different thicknesses, for PVC, film and other fine is generally one time, for rough things such as cloth to thickness printing suitability, otherwise it is easy to break.

Seven, screen printing machine screen edition publishing

Pay attention to the integrity of each character, and smooth, such as tooth lines and other reasons, require high precision, the version will have to be re-printed!
