How to buy ctp equipment?

Prepress technology includes only part of the ctp technology, but this part is the basic requirements, currently Creo, Agfa, Screen, Heidelberg, Fujitsu and other companies provide thermal and photosensitive devices. When selecting ctp, these factors must be taken into account.

1. Arrangement page: You must arrange the postscript file of the page yourself to prepare the digital plate. Conventional prepress systems need to be upgraded to support page layout. At the same time, some software is needed to keep track of all the elements.

2. Group Edition, ie, imposition: Loading multiple pages on a plate requires that the pages be electronically assembled before platemaking. There are many ways to implement a build. You can redefine the layout template to meet the needs of the page, as well as custom solutions based on opi. No matter how the process of making a group is completed, the work will be changed from the current mode of plate making to digital publishing, thus enriching the prepress area.

3. Production load capacity and deadline: The so-called production load force refers to the output capacity that the equipment can withstand, and the deadline is the time limit for completing the entire single job. Which need to consider the computing power of each individual file in the page.

4. Proofing: Since it is a ctp process, we must consider the use of digital proofing. For some of these technical factors, digital proofing is also used as a basis.

5. Calibration: The calibration basis of the ctp is almost indistinguishable from the traditional printing plate, except that the ctp standard is replaced by numbers, and the dots are only measured by the plate density meter.

6. Separation settings and halftone screening: Adjust the separation settings to determine dot gain values ​​and ink coverage. Ctp can abandon the traditional AM network, and take full advantage of FM opportunities brought about by the perfect opportunity.

7. Plate Punching: An independent drilling system will satisfy the requirements of different printing machines. Most ctp systems have this option.

8. Ink data tracking: Many printers use the plate scanner to set and determine the ink trace data for the initial printing; in ctp, the rip calculation determines and stores the ink trace data cip3. This data is used to generate a histogram. , as an important help in setting up printing inks.

9. Equipment plate-making output speed: The published quantity per hour is a problem considered by most manufacturers, but these problems have been solved and the speed is not a problem for ctp manufacturers.

10. The convenience of software and equipment operation: software should be developed on the basis of traditional prepress, then the operation of software should also be based on ctp; the operation of equipment also follows this principle, which greatly reduces the post-production Trouble with training.

11. The format choice of the equipment: This is totally a matter for independent consideration and matching of the company. Of course, this should also be considered with other relevant factors (such as whether it is online, whether it needs layout proofing, etc.).

When we really choose the ctp system, the factors we need to consider may be more extensive according to our actual situation.
