About JDF, CIP3 and CIP4 book understanding

<

Chen Tieming, a graduate of the Physics Department of the Chinese University of Hong Kong, once went to the United States to receive prepress-printing training. He used to work as a prepress application engineer for Kodak's Asia Pacific region, and later served as the Sales Manager for Sailing Angel Hong Kong. His current position is Kobe Digital Prepress Technology Sales. manager.

In 1995, it was agreed by several suppliers to develop standardization of electronic process management. It has been eight years since today and it can be seen that this driving force will still greatly promote the improvement of the overall printing industry in the future. Therefore, the author hopes to make a review and provide some basic information here so that readers will have easier access to this tool in the coming days.

Everything starts here: "International Cooperation for Integration of Press, Press and Postpress" (CIP3)

CIP3 Agreement Major Achievements - PPF

In the actual printing trend, electronic, short editions, color requirements, cheaper prices, etc., have driven the printing industry to become electronic, thus avoiding any possible mistakes and manual participation. For example, the data input by human hands, the data processing of the inks scanned by the ink and the cross-positioning registration, etc., all hope to be electronically computerized in one step. Therefore, the PPF came into being.

PPF is the Print Production Format, a computer data protocol format used to make a common electronic data format for different working platforms, making communication more direct and avoiding errors and time waste in data transfer and copying.

This has led to the development of a concept-CIM (Computer Integrated Print Management), which is computerized overall management.

PPF working area

What PPF knows best is the electronic ink drop management. In addition, the following information can be generated depending on the electronic board-making process with different functions. The 3.0 version of PPF developed in 1998 can support:

Work Order Management Data

Ink key data

Cross and color management ribbons

Roller printing operation data

Knife and origami style

Receive paper

Nailing style

Basically, it can be said that after the data is produced from prepress, it can provide the information needed for printing and post-pressing. However, there are still some things that are not perfected. They are implemented in the real world, with different interfaces, different suppliers, and different considerations. How can one be unified under one agreement?

The CIP4 was established in February 2000 and was released by JDF. In the same year and later in Drupa, major suppliers and developers reached a mutual agreement and later produced CIP4.

JDF : Job Definition Format

CIP: Processes in Prepress, Press and Postpress

It can be seen that the PPF, which was originally only a concept, obtained Processes here, and the JDF of CIP4 also became the agreed standard of major equipment and software suppliers.

Where does JDF come from? Perhaps your first answer will be the prepress process system. Correct! But it may also be a print buyer, because you may be printing for the second or third time. So your prepress process should have the ability to manage JDF.

All departments, such as postpress and printing, have different degree of computerization of their hardware. Is there any modification or editing function besides considering the input of JDF?

How can we guarantee that the data will be applied smoothly and smoothly in different language interfaces, different regions, different brand suppliers and different users?

Is the concept of such greatness practical and feasible? How long do we need to wait?

The redistribution of all parts of the staff, whether it is necessary to nail the master computer learning automatic folding and folding machine?

What if the old machine does not have a JDF computer?

Finally, things must move forward, especially when printing such technology-intensive industries. Drupa should pay attention in the following year.
