Five advantages of packaging and printing enterprise application of CTP technology

For packaging and printing, the advantages of application of CTP technology basically has the following several aspects.

1. Reduce the cost of plate making

Now some brands, such as kodak, Fuji, etc.) of high quality thermal CTP plate prices generally in 35 yuan/square metre, than ordinary PS version of a slightly higher price, but is much lower than special UV printing PS version.Now, high-grade packaging carton and cigarette package printing mostly use UV printing, basic does not use ordinary PS version, so the application of CTP technology, plate prices has not grown much.And CTP plate making out the film output process, save the cost of film, so more price advantage. 

2. The ascension process speed and quality of plate making

With newspaper () the content of every day is different, product packaging finalized after generally will not easily change, there is a plateau, and ordinary plate making the film in the stable period can be repeated use, although CTP plate making out the film output process, but it is difficult to match in this respect.However, CTP technology to a certain extent, has raised the plate-making speed and quality of plate making, mainly reflected in the following several aspects. 

(1) to avoid the film output process, because of phototypesetter precision, film exposure, developer and fixing bath concentration changes caused by the error. 

(2) to avoid the common plate making process, the film caused by printing machine vacuum is not enough and the joint plate is not quite close together, leading to plate line breezing phenomenon;Avoided by film aging yellow underexposed or plate on the film edge mark problems;Avoided for plate burning machine glass is not clean or film caused by not clean the surface of the plate dirty point problem. 

(3) reduce the ordinary plate making process, each time to pick the film, the laying of artificial measuring film on the plate position need time and chance to make mistakes, and hand finish mark the edge of the plate and film dirty point on time. 

3. Improve the printing version of speed and quality

Because the CTP plate making positioning precision, so the CTP plate after computer basic don't need to adjust, greatly improves the speed of version, at the same time saves the version of the paper.And CTP plate overprint accurate, clean the dirty plate surface points, good network reduction plate itself, layout of good ink, resistance rate, improve the quality of printing. 

4. Guarantee the alignment precision between each working procedure

Packaging printing process is more complex, often generally takes 3 ~ 5 working procedure, production cycle is long, as a result of the paper is difficult to overcome shrinkage, so during the bound to change the size of the paper.Moreover, the accuracy requirement of the packaging printing on print is higher, especially high-grade packaging box (especially the packaging carton) is used for automatic packaging machine is high to the requirement of design of symmetry and dimensional stability (error within + / - 0.5 mm).To this end, we often need to vary according to the size of the each batch paper to adjust the printing blocks, to offset paper alignment deviation, as a result of the increases with the CTP, this adjustment is convenient, quick, thus effectively guarantee the alignment precision between the various working procedures, and print the patterns of the symmetry and dimensional stability. 

5. Ensure that tobacco package version proofing and design proofing timeliness

Although cigarette packet printing HuoYuan stable, affected by tobacco policy and international environment, from the point of nearly 10 years of history, the tobacco industry will have 1 ~ 2 times a year an industrywide revision "movement", the ZhongYan companies in order to retain the original market share as well as the "open its soil", is doing its best to develop new products, and each cigarette packet printing enterprise in order to get more "cake", are also actively meet ZhongYan company, work hard for cigarette package design and development.Whether old cigarette package revision of proofing, or new cigarette package design proofing, by convention, ZhongYan company need is finished product sample, in the modern times, "not enough" deliver faster to "eat", but also can not delay the delivery time of existing products, at this time is even more underlines the CTP plate making workshop of clean technology advantage.
