This is a common phenomenon in recent years. Every year, many enterprises will start to design their own calendars, which is a new way of publicity. However, from the perspective of the printing industry, these enterprises have some problems in desk calendar printing and wall calendar printing. Today, I would like to talk about some factors that affect the printing color of Jinan desk calendar.
1. Platform for color conversion
Have you ever encountered the problem that the customer gave us RGB files? How can we convert them to CMYK? If each printing company uses different conversion standards, the converted CMYK files will have different colors. Secondly, even for the same document, the color of desk calendar and wall calendar will be different through digital printing, offset printing, gravure printing and other different printing methods.
2. File conversion
The difference in the total number of dots may also affect the color effect of the final desk calendar printing and calendar printing. In addition, different screening technologies make different screen types have different dot gain rates. For example, if today's CTP equipment is broken, you can use another CTP to publish, and the final desk calendar printing color may have a certain amount of difference. This is unavoidable.
3. Publishing process
Because of the different definitions of plate manufacturers' technology, screening type and dot gain, different exposure rates of plate mesh points and printing equipment will affect the quality of printing plates. If there is no uniform standard in the publishing process, it is difficult to make every batch of desk calendar printing and wall calendar printing the same.
4. Differences in equipment
In the printing process of desk calendar and wall calendar, we also neglected one factor: the dot gain rate of equipment.
The dot gain rate of printing equipment in each printing factory is different. That is to say, even if you are given the same set of plates, the same substrate and consumables, you may not be able to get similar prints on different printing presses. Therefore, it is very important for relevant operators to understand the concept of dot gain rate. CTP can not only collect various data, but also compensate nodes.
5. Paper quality
Only when each batch of paper is inspected at the time of purchase, and these inspection data are handed over to the paper vendor, can we have the power to supervise and urge the paper quality to be better and better. Ensure that the paper is qualified.
6. Ink quality
Different inks have a great impact on the quality of desk calendar printing and wall calendar printing. Niu · She · Wang · The fluidity of each ink is different, and the color of the ink is also different. Printing enterprises should also have corresponding measurement and statistics when purchasing each batch to ensure the stability of the quality of different batches.
In general, a good desk calendar printing should pay attention to color conversion, file conversion, publishing process, different printing equipment, paper quality and ink quality. Only by paying attention to these six points can we print a better desk calendar.
