We have been engaged in computer platemaking for more than a year. We have been using Wits software. The version has been contacted from 2.1, 3.0 to 3.1. Through this period of work practice, there are some experiences to talk with everyone. Let's talk about the color version first. Production.
For offset printing workers, the printing of black ground is relatively laborious, and there are often inconsistencies between the front and back, with bubbles, ink and other phenomena, affecting the appearance of printed products. We have adopted the following method to improve, that is, in the process of plate-making, add 40% of magenta and yellow and 50% of cyan to the black ground, which can greatly reduce the quality problems caused by the above factors in the printing process. .
Making a spot color version is a lot more important than normal four-color printing. A separate color version is required for the tape. This has the problem of whether two-page content can be completely registered. This type of problem is generally divided into several cases. If it is a text, increase or decrease the level by one on the "thickness" option; if it is a picture, use the ruler to pull the line to catch the register; if it is the base color, it will be on the bottom. One-to-two lines are included in the color. The above measures are to solve the phenomenon of over-printing that is not allowed due to overprinting during the printing process.
Sometimes, a single-color version will be produced because of customer's request. In fact, the so-called monochrome version is another spot color version. For example, customers want to print red and gold. At the beginning, we need to re-color the final version after the customer's finalization. In fact, only a single color product is needed. Red version can be.
The other is the calculation of an angle plus volume, which involves the issue of paper in the printing format.
General photojournalists mostly open format, so that the size of the row A4 in the senior year open layout does not need to consider the angle plus volume, but if you encounter special circumstances is not the same. For example, a large 32-single-single cut, if you still press the Wits software's default 3mm typesetting, then the rules line around the layout will overflow the print, resulting in failure to register.
In the end, we have made a few small suggestions for the system of the Founder of BeiDou:
1. Improvements in display mode
The old computer models are relatively old and their performance is relatively low. If the display mode is too high, it will take a lot of time during operation, but now the speed and performance of the models have increased a lot. Therefore, it is recommended to improve the accuracy of the display mode. WYSIWYG.
2. The fine positioning of some operations in the Wits software is not good enough. For example, the extension line layout on two concentric circles (diameter of 5mm, 8mm, and 7th character), the image on the monitor is very positive and can be sent out. The pattern has deviated.
3. As an advertising creative, Wits' font type is still less, so it is recommended to make an improvement in the diversification of font effects.
4. Diversification of support for location formats also needs improvement.
5. The typesetting subsystems of tables, mathematics, chemistry, etc. will have some problems in the actual operation and hope to be improved in the subsequent versions.
In addition to the above experience, by the way, it also tells you a small trick: move the cursor to any button of the toolbox (except the arrow, pull pressure and hand buttons), you will get unexpected results, give it a try.
