What should we do if the heat transfer paper manuscript has a color cast during the digital printing process?
Usually in the production process of thermal transfer paper, many digital printing factories may encounter the problem of offset color of the original, which is also a problem that has long plagued the manufacturers. Today, let me help you solve this problem, and hope to help more users solve similar problems.
Q: What should I do if the transfer paper manuscript is blue and purple?
A: You can use color filters to correct. Scan the light yellow filter with appropriate density and paste the color cast original and the light yellow filter together on the scanning cylinder for scanning color separation. If it is high-key, it may be yellowish. Use white balance or high-adjustment. The target method can be corrected.
PS: This method is more effective in correcting the color cast of the neutral and dark adjustments, but it should be noted that interference occurs when the color filter and the original overlap are not real, such as Newton's ring.
Q: The sublimation paper has a color cast. After the high and low recording density settings, the color correction knob cannot be fully proofed. What should I do?
A: You can use the method of changing the level to correct it. That is to say, the level of the center tone can be appropriately changed by the method of hierarchical proofreading, thereby improving the problem of gray imbalance caused by the false color of the original. For example, if the original is blue-violet, we must first determine the total height, medium and low position of the original. The thermal transfer paper will find the ambiguous gray balance data according to the post-process, thus improving the center of the green plate and correcting the deviation. Color problem.
PS: This method is suitable for the landscape type of the original is blue, and the portrait-like original is purple when the backlight is backlit. For reddish originals, the method of brightening the magenta version of the center can be used to correct the color cast problem.
