Preparation of digital documents before silk printing -- making some different types of pictures suitable for silk printing

someone once said, "advanced technology and magic are similar." Silk screen printers who use digital prepress technology are like magicians, transforming documents provided by different customers into pictures suitable for printing. This is a very useful technology, but it is not so simple to master it correctly. Usually, silk screen printing workers use documents designed by others for making pages or for offset printing, and there are few documents specially designed for silk screen printing. Therefore, we have to adjust the document on the premise of losing quality in order to complete the task. However, it is often encountered that although the originals provided are not used for silk screen printing, customers strongly demand that the quality of printed products after silk screen printing cannot be reduced. Although sometimes we hope to strengthen the communication with customers through salespersons, unfortunately, salespersons usually don't understand the subtle differences between digital originals used for silk screen printing. They think that as long as the customer puts forward, they should accept unconditionally, regardless of what kind of originals the customer provides. In fact, because the documents we receive are not prepared for silk screen printing, and it takes quite a long time to process, we only spend a little time on prepress and production. The defects of the file mainly include the following situations: 1. Incorrect pixel positions or white patches, which make it necessary to redo the image in a wide range but more comprehensively, although there will be no problems and new adjustments in a short time; 2. Image resolution not suitable for printing size; 3. The color separation setting for lithography or other purposes is little or can not meet the color requirements of silk screen printing; 4. The digital image proofing result is inconsistent with the final screen printing result. The above are common situations. We can take several specific measures to improve the quality of documents and the efficiency and accuracy of the whole process. Whether the image is designed for screen printing or for other purposes, the most important thing is to optimize the document used for production and prepare it quickly and accurately. When dealing with electronic documents, we must pay all attention to some elements, because most of the digital originals used for silk screen printing are from image documents used for other purposes. In addition, a more practical method should be found to speed up, improve quality and output product consistency. This method should be independent of the processing process or the original use. Digital workflow digital workflow is the most important consideration. It is related to the speed of processing an operation in the prepress process, the difficulty of processing digital documents, and the methods and steps used by prepress technicians to prepare silk screen compositions. In the current production conditions of construction machines and tools, speed and production efficiency are the most important issues, which are closely related to the computer technology that has maintained the growth momentum. It is predicted that by the 21st century, we will use desktop computers with more than 800MHz (high-end workstations, such as Agfa Dec, currently run at a speed of more than 1000MHz, but its price is too high, much higher than desktop computers). By then, the time for preparing documents before silk screen printing will be greatly shortened, said Slater, now 23
