What is the pre-printing preparation of tag coated paper?
The pre-printing preparation of tag coated paper is an important link to ensure the quality and efficiency of printing, mainly including the following aspects:
1. Design draft confirmation
Design completed: By professional art software (such as Adobe Illustrator, Adobe Photoshop, etc.) will be the tag layout design, and through the customer or internal audit to confirm the correct.
Proofing confirmation: Before mass printing, proofing operation is carried out to make samples of products for confirmation. Proofing methods include proof press proofing, simple proofing, digital proofing and so on. Samples need to be confirmed by the customer or relevant personnel to ensure that the desired printing effect is achieved.
2. Preparation of printing materials
Coated paper selection: Select the appropriate coated paper according to the design draft and customer needs to ensure that the quality of the paper meets the printing requirements.
Ink preparation: Check and prepare the required ink to ensure that the color and viscosity of the ink meet the printing standards.
Three, printing equipment inspection
Equipment cleaning: clean the printing site, ensure that there is a certain operating space around the printing press, and avoid other objects to hinder the work. At the same time, check and clean the printing equipment to ensure that the equipment is in good working condition.
Parameter setting: According to the characteristics of coated paper, adjust the parameters of the printing equipment, such as printing pressure, ink supply, etc., to ensure the printing quality.
4. Preparation for printing
Film production: The design draft is printed on PC film through the equipment to make film as a printed negative.
Printing and inspection: The use of film to print the operation, that is, to copy the text and text onto the screen plate coated with sensitive materials. After printing, it is necessary to carefully check the quality of the printing plate to ensure that the graphics are clear and no ink leakage phenomenon.
5. Environmental control
Temperature and humidity regulation: Adjust the temperature and humidity of the printing shop to the appropriate range, the general temperature is 18 ~ 25 ° C, and the relative humidity is 40% ~ 65% to prevent the paper from hygroscopic deformation or poor ink drying.
Ventilation and dust prevention: maintain good ventilation conditions in the printing workshop to reduce the impact of dust and other impurities on printing quality.
6. Personnel training and safety preparation
Personnel training: Conduct necessary training for printing operators to ensure that they are familiar with the printing process, equipment operation and safety specifications.
Safety inspection: pre-printing safety inspection, including the effectiveness of fire facilities, emergency evacuation channels, etc., to ensure the safety of the printing process.
In summary, the pre-printing preparation of tag coated paper needs to be comprehensively considered and effective preparation measures implemented from many aspects such as design confirmation, printing material preparation, printing equipment inspection, printing plate preparation, environmental control, personnel training and safety preparation. These preparations are essential to ensure print quality and efficiency.
