How to judge whether the baking degree of silicone thermal transfer trademarks meets the standard?
To judge whether the baking degree of silicone thermal transfer trademarks meets the standard, you can start from the following aspects:
Observe the appearance:
Pattern clarity: When it meets the standard, the edges of the thermal transfer pattern or text are clear and sharp, without blurring, ghosting or diffusion. If the pattern edge is rough and the color is weak, it means that the baking may not be enough and the ink is not completely fixed; if the pattern color is too dim or there are traces of burning, it may be over-baked.
Color brightness: A qualified trademark should have bright and full colors, close to the color of the design before transfer, without obvious fading or discoloration. If the color is light, it may be insufficient baking and the ink has not been fully attached; if the color is abnormally darkened or black spots appear, it may be that the temperature is too high or the time is too long.
Silicone surface state: The surface of the silicone should be smooth and flat, without bubbles, cracks or deformation. If there are bubbles, it may be that the temperature rises too quickly during the baking process and the gas is not discharged in time; cracks or deformations indicate that the temperature is too high or the time is too long, and the performance of the silicone is damaged.
Touch feeling:
Firmness of pattern: Touch the surface of the pattern with your fingers gently. If you feel that the pattern has obvious bulges or can be easily scraped or rubbed off, it means that the ink is not completely cured and the baking degree is not enough. When the standard is met, the pattern should be tightly combined with the surface of the silicone, without obvious bulges, and not easy to be scraped off.
Silicone texture: Normally baked silicone feels soft and elastic. If the silicone feels hard, brittle, and loses elasticity, it means that it is over-baked and the physical properties of the silicone have changed.
Perform a peeling test: Carefully try to peel off a small part of the transfer pattern from the surface of the silicone (in a part that does not affect the overall use of the trademark). If it can be peeled off easily and there is little ink left on the surface of the silicone, it means that the baking is insufficient and the adhesion between the ink and the silicone is not enough; if the pattern is difficult to peel off and there is more ink left on the surface of the silicone after peeling, it means that the baking degree is good and the pattern has been firmly transferred to the silicone.
Simulated use environment test: Place the baked silicone thermal transfer trademark in a specific simulated use environment for testing, such as soaking in water for a certain period of time, washing with detergent, and placing it in a high or low temperature environment. Observe whether the trademark pattern fades, falls off, or whether the silicone is damaged after these tests. If the trademark can maintain a good condition under the simulated use environment, it means that the baking degree meets the standard and the product has good durability.
Compare with standard samples: Make standard silicone thermal transfer trademark samples, compare the baked products with standard samples, and make detailed comparisons in terms of appearance, feel, firmness, etc. to determine whether the baking degree is consistent. If there is a significant difference from the standard sample, the baking parameters need to be adjusted.
