im a student of Faculty of grafic arts, and one part of research is about best CTP platewriter (brands) , prepress workflow, proofs... i want to know about those from last 2 years, because i have old literature that is 10 years old, and not reliable now... at least 5 of these for each.. your opinions at least.. ty

As with any evaluation, you first need to list the criteria you will use to determine "best." Then analyze the features and specifications, and perhaps anecdotal evidence, of the various devices and workflows according to your criteria.

best, gordon p

As most reliable devices, and most famous in this moment.. who has leading industry in CTP sector..

If you are asking which company sells the most CtP devices - that's probably Screen since it's also sold under different brand names.

One could argue that if you ask which company sells the most hamburgers - that's probably McDonald's. Does that make a McDonald's hamburger the best hamburger?

but it makes them leading in their buiseness.. like burger king etc etc...
thats what i want to now, which one sell most (if u can name 5 pls)? i know its not necessary best in quality..

this one will be tough. We can start by asking if its the cheeseburger (Fiber diode) double cheeseburger (GLV) or hamburger (Canned Diode). I can state that all sales for CTP have hit rock bottom in the sales department. As for reliability each machine is different because of the demand on the machine and the enviroment it is in.

by the way is there still 5 out there

i am not looking for individual ctp devices or types.. i want to know which company have highest participation in producing and selling.. as i can see its kodak, screen, agfa, creo... just want to know, by your opinion which are?
one more question, i saw CtcP technology, what is that exactly, is that knew or?

CTP (Computer to Plate) CTcp (Computer to convetional Plate)

the old analog plates as we used a light source 800-850 NM range of light using film
and a vacumm frame to expose the plate then process through a processor using developer. (mostly chemistry of a soap base devloper is what I like to call it)


CTcp is using the analog plate with a high power UV light

At Drupa 2004 there was a new Espresso CTP product from Esko-Graphics. Conventional printing plates are imaged, this is CTcP, using a UV lamp as its light source instead of high priced lasers and digital plates. Esko's thinking was that Imaging conventional plates digitally is the future,

Esko's Espresso was built on there current hardware of the Eskoscan copydot scanning product. That product for scanning screened film at high resolution was a very good reliable machine. This was a copy dot scanner

how they did it was that the plate was to be manually loaded and unloaded, thus aimed at small shops. a small light or edge detect would ensures plate registraion, then it's imaged. a digital head was installed with Digital Mirror and a lens. This unit images the pixels from digital data exposing to the conventional plate. Esko's UV head sweeps back and forth on air bearings. The head has redundancy in the Digital Mirrors.

This was aimed at the hundreds or maybe even thousands of esko scanners that where already in the field. The scanner has a low fail rate. The Luscher and Basysprint
is based on the same technology

I hope this helps

tnx

is there any other new tecnology similar to ctp? in the past 2-3 years.. i found only iCTP..

[Raymond Ramirez]

only Processless and low Processor... Agfa's Azura TS is starting to hit the market with very good results. This is a Latex base emultion that melts the emultion to the plate..
