Straight output spiral correction in CTP plate making

If one day after the printing process, you pick up a sheet of paper and look at the light. Carefully, you will find that there is a straight line from piercing to dragging. Now it is printed as a diagonal line. You come across a more discerning buyer's e-surveillance code, which may be subject to deductions. If it is a bad thing, the buyer may not receive the goods. At this point, you are in a hurry to go to the electronic monitoring code of the printing shop, ask the master, is not the paper deformation, or the deformation of the plate, the printing plate is the use of the CTP plate, the hole also uses a cross Bit-perforated RFID should be accurate! The master is right, and the plate-making staff is not wrong. Where is the problem at the end of the time? Where is it?

We know that most CTP platesetters on the market today, whether they are thermal or UV, are based on external drum design and printing reports. This bending and clamping of the plate in the way that is closest to the printing machine can be completely consistent. High-quality dots; but based on this type of drum-like design, a straight line offset in the X direction is generated when the full-line straight line from top to bottom is output, resulting in an oblique line after the line is finally exposed to the plate. To say that if you want to expose a rectangular KBA, what is now exposed is a parallelogram. This deviation is negligible for normal paper prints, but for prints with higher quality requirements, this deviation may be very useful to you. Big loss.

For this parallelogram problem printing accessory, the CTP platemaking apparatus must compensate for this distortion, so that the output plate is a straight line from top to bottom.

Aisike’s R&D engineers knew this problem early enough and developed the straight-line output spiral correction function early on. Engineers used accurate calculations to seamlessly embed this function into the device control Konica Minolta. , Allows users to achieve the perfect straight line when outputting plates.
