Projection exposure template making technology

One of the highlights of a visit to Murakami’s silk screen printing company in Japan was a large advertisement for a 2Mx4m, which was made with the company’s high resolution.The SBQ photosensitive adhesive with high sensitivity is coated and dried by an automatic gluing machine.It is printed with a large template made by the automatic projection exposure mechanism manufactured by Murakami.In the past we made large color ads.Due to the camera. The extension, the largest format can only be fully open.If you want to make large print advertisements, you can only adopt the method of splicing. Of course, there are certain limitations.So the new technology created a new situation for the production of large – scale color advertising pictures -IF.The process steps of projection exposure platemaking are: use the usual

Color separation method to add positive picture.Then magnify the screen image and project it to the screen template respectively, and then make the screen printing plate. It only takes 4 minutes to expose a 2m×Am screen template.Projection method: one used for making large-format printing plates.Posters, etc.Saving time and effort completely saves the cost of film for ordinary platemaking.For example, make a screen printing plate with an image area of 125× 175CNm (2.2m”) — a 12.5×17.5cm(o.022m “) positive image enlarged by projection exposure.Compared with the original dayang picture contact printout method.Can save 90% film cost.The projection exposure method not only saves the cost of the film – but also eliminates the exposure and development of the film, thus saving the cost of the chemicals used to develop the film.In addition, due to the cancellation of film exposure and development.This eliminates any deviation from the film due to inconsistent development and exposure.In this way, the problem of large – scale advertising splicing is solved.There is no problem of inconsistent ink splicing between two adjacent prints, which improves the quality of the prints.Of course – screen printing plate made by projection method. The precision of the image dull point will be limited by a 50 line/cm tuning point. After magnification of 10 times, the precision drops to 5 lines/cm.For large outdoor ads, however.Most are viewed from a distance of 25 or more, this

The fineness of the sample is still ideal for visual effects.Some statistics such as a screen drama factory a day high 10O film.If the tablet costs 15 yuan, it will cost 1,500 yuan a day.If you use computer direct projection platemaking, you can reduce 90% of the film, so that you can save 400,000 yuan a year.Due to direct projection equipment sub-edition to screen printing industry has brought a lot of benefits, many companies at home and abroad.Especially for large screen printing advertising companies.Due to the current electricity or desktop publishing system to produce four color separation positive bottom version of the maximum size of more than a full sheet of paper.It is very easy to make 2m×3m template format by projection, so many companies engaged in large-scale screen printing sword purchase screen printing projection plate-making equipment.Beijing Jingxi advertising center took the lead in the purchase of a set of Murakami company’s projection exposure production template equipment, I believe it will become a large screen printing drama projection center.
