Overview
Offset plate inks Spot Color Proofer (fixed type) is a device designed to imitate the printing press Working Principle, with adjustable pressure and a wide range of substrates. It accurately predicts inks Hue through standard proofing, and compares with master standard to determine the inks ratio, so that the color scheme work is converted to pre-press work. It is suitable for Encasement printing, papermaking, inks production and scientific research institutions.
Features
1. Adjustable pressure to adapt to different substrates; 2. Automatic proofing method to improve efficiency; 3. Adjustable proofing speed to support frequency conversion speed regulation; 4. Adjustable ink leveling time to optimize the proofing process; 5. Fixed design, stable operation.
Principle
The Proofer imitates the printing press Working Principle and predicts inks Hue through standard proofing. During the operation, it is constantly compared with the master standard Color to determine the correct ratio of inks and realize the prepress color scheme. A fixed direct transfer method is used to unify and transfer the ink at one time to ensure the accuracy of proofing.
Applications
Encasement printing production, paper production enterprises, inks production enterprises, scientific research institutions
Standards
GB/T 8941、ISO2813、ISO 2469、ISO 9416、GB/T 7973、GB/T 7974、GB/T12911、GB/T7706、ASTM D 6531
Steps
1. Prepare printing materials and inks; 2. Set proofing speed and pressure; 3. Adjust ink leveling time; 4. Start automatic proofing; 5. Compare Color with master standard; 6. Determine ink ratio.
Notice
• Proofing pressure needs to be manually adjusted according to roller abrasion or old and new conditions; • Ensure stable placement of equipment before use; • Regularly check roller specifications and abrasion; • Follow standard operating procedures to ensure safety.
