Yes, but this can be compensated by adjusting the calibration curve of the platemaking equipment before printing.
UV printing can meet the current requirements of ISO12647-2 four-color printing?
Yes, but it must be specified when ordering UV four-color printing inks.
Is there a problem with printing UV prints?
No, when the printed sheet reaches the delivery, it is already dry, so no dirtiness will occur. Pay attention to the efficiency of the luminaire and it is not necessary to clean it.
Can UV prints be recycled?
UV prints can be treated like other printed waste products, with the same heavy metal content and biodegradability; even thickly coated sheets can be processed with the pulper currently used in the float process.
Can it be used in toy packaging?
Yes, when ordering UV inks, specify “Toy Packaging†so that the supplier will select the appropriate color (the same process as traditional inks).
UV products suitable for food packaging?
The special UV inks and varnish that are used exclusively for food packaging meet high requirements in odor and smear tests. To obtain compliant results requires proper curing, careful control and good processes. However, the European printing ink industry still recommends no direct contact between the printed surface and the food. Even if the risk of diversion or relocation is very low, direct contact should be avoided.
How do UV inks and varnish odors and smudges compare to other products?
UV's unique advantage is that it can be quickly stabilized by measuring the standard test methods that have been proven by food manufacturers. The correct lead time required to get a properly monitored UV print between printing and the packaging required by the industry is short. Cured UV products also have a very low potential for problems with odors and smudges.
Is there a problem with ozone production?
The UV lamps are equipped with an exhaust system that emits a very low amount of ozone from the workplace. The equipment used must be properly maintained. Ozone is easily detected and daily testing is recommended.
Does the UV printing process create other emissions problems?
Ozone is the only emission; odors are generated by lamps, and each UV unit is usually equipped with a discharge device. Compared with traditional printing, UV printing emits less volatile organics into the air and can therefore be used as a control technique.
Is there a problem with ink mist produced on a quick press?
There are many factors that can affect the amount of ink mist produced. Ink spray should be avoided, at least to a minimum, because it affects health, cleanliness and hygiene. High-speed printers should be equipped with ink mist discharge devices. Good maintenance of the press, including roller, plate and blanket cylinder pressures, printer temperature control, effective exhaust ventilation and general ventilation, will further reduce the amount of ink mist generated.
Are UV products used in the same way as traditional inks?
Energy-cured products can be treated in the same way as oil-based products and water-based products and are subject to the same high standards of hygiene and handling requirements. Need a good housekeeping standard, be careful to avoid unnecessary exposure to UV products. Always read the health and safety information provided by the supplier and follow it carefully. If you do not comply with the recommended method of use provided by the supplier, you may experience eye irritation in the environment with uncured UV products for a long time.
