About us

  • We are the platemaking equipment manufacturer which have provided “equipment and environment” for one of the biggest screen platemaker in Japan for a long time. While Japan’s know-how in electronics industry is utilized throughout Asia, the screen printing supports the foundation of the electronic industry. Our equipment, especially the screen mask, plays a key role in field of screen printing. Although platemaking equipment can be purchased anywhere, you may wonder, “Can a company make the high-precision screen masks? Doesn’t it take too long?” We contribute to the manufacturing technology development with our “screen printing technology”.
  • With experience as a platemaker, we have accumulated know-how in “platemaking equipment and technology”. We manufacture equipment ranging from “mini component series” which needs only 1 pyung to be installed to “PDF screen masks” which corresponds to 2,500 mm aluminum frame.


  • The step is to introduce equipment and technology of screen masks. For the first step, the platemaking process is introduced. Although PS plates (presensitized plate) need to be purchased, the equipment investment can be reduced by 1/3. A printer and a developer make platemaking in a company possible, which is the great merit. If PS plates are in stock, a screen mask is completed within 30 minutes. A film negative is kept in a company so that confidential film is not leak. Go to Example of Layout and necessary equipment (for laminating and developing process).

Fulfilling supports. Protec Engineering provides all things in a faithful way.

Screen mask manufacturing requires long process and preparation of both hard and soft sides. We coordinate all the process ranging from screen mask manufacturing equipment arrangement to screen mask manufacturing method, which saves you all the troubles. Regarding manufacturing, we provide you for all the necessary tools and chemicals and inform you for how to use them and to deal with problems. Even after a project finishes, we keep supplying you with materials and helping your troubleshooting. We can enable you to embark on your project with confidence.

Screen mask technology guidance

Plate making has a general part and a recondite part including various know-how. We prepare the outline of platemaking technology guidance including “high efficiency, good quality guaranteed, and combination technique” apart from the guidance to use manufacturing equipment. The guidance is divided as follows.

Sample Layout

We’ll advise the best lay-out for your plan, from the compact mini-comp to the largest-scale facility of PDF screen mask.


We can provide all materials that are qualified as high performance.
(Introduced materials are as part of our articles for sale.)
Processing of new frame Full-removal of grease by aluminum frame cleaning chemical to boost adhesiveness
Undercoating of frame High reliability gained by electrometric adhesive for frame undercoating
Mesh Provide polyester mesh with high performance.
Adhesion with frame Prepare and use electrometric adhesive and instantaneous adhesive properly.
Drying adhesive Powerful adhesion by hardening accelerator that is exclusively used for instantaneous adhesive
Combination Adhesive for combination with clean finish and stable result
Intermediate materials for combination Increase working efficiency with several types of tapes and sheets for special purposes.
Mesh cleaning chemical Mesh cleaning at first for high quality coating
SUS surface processingagent Smooth coating by surface processing agent for stainless mesh
Dustless cloth Dustless cloth is an indispensable item for handling emulsion.
Antistatic adhesive roller Adhesive roller can also eliminate static electricity.
Antistatic brush Remove static electricity out of glass surface and film injust about no time.
Water repellent coat Surface coating agent to protect against clog or blur, and make screen cleaning and screen detaching easy
Glass cleaner Printer glass can be cleaned before printing as well as removal of electricity.
Film strengthening chemical Respond with severe printing environment by strengthening films by chemical
Solvent stripper Strips hardened film after printing at once for reuse.
