Computer To Plate
General information
We have
acquired a Swiss CtP system Luscher, Xpose! UVconventional for digital imaging
printing plates.
Maximum plate size is 1130x950 mm, minimum size is 500x360 mm, and available
plate thickness ranges from 0.15 to 0.40 mm.
This platesetter uses 32 laser diodes, emitting monochromatic blue light beams
with 405 nm wavelength.
Imaging resolution is 2400dpi.
Perfect consistency from plate to plate is achieved by an automatic positioning
system based on the symmetric plate input (plate centring) or by using
pre-punched plates (Bacher 2000 system).
Our plates are processed by Raptor 85 Thermal plate processor from Glunz&Jensen.
Raster image is prepared by Harlequin Torrent RIP v.6.0 sp4 with integrated trapping function (Trap Pro module).
We use PDF Organizer B1 Pro from AC&C HSH Group to assemble and impose sheets.
For proofing purposes we have installed GMG ColorProof 04 system and EPSON Stylus Pro 9600 inkjet printer, controlled by GMG ColorProof 04 8UP software. This system can produce contract-quality proofs, which can simulate production results, while it may also be used for colour imposition proofs.
Technical requirements for jobs:
1. Detailed description sent along with the data. The description has to include: trimmed page size, screen ruling required, screen angles (if non-standard), required spot colours (exactly named) and full-scale preview or hard-copy.
2. File format: PDF files only, conforming to version standard up to 1.4.
Colour jobs (including spots) should be saved as Composite CMYK (unseparated). Black-only jobs should be saved as Black & White or Greyscale (if screens are used). File names should match intended usage (like „Page01.pdf”). Only basic ASCII characters (ie. no accents) are allowed in the file name..
3. Please use Acrobat Distiller to generate PDF files (saving result as PDF 1.4).
4. Every page should include cut marks, registration marks, and separation names.
5. Files should be prepared for imaging resolution 2400 dpi and screen ruling 150 lpi (unless other screen ruling is required).
6. Any bleeds should be at least 3 mm larger than trim size.
7. For advertising, bleeds must be used on all four sides.
8. For perfect bound jobs please remember that inside covers, as well as first and last pages of the book block, will be glued for up to 6 mm from the spine side (side gluing). Please design these pages accordingly so that this area is free of ink.
9. For spreads, please send separate files for left and right page of the spread.
10. Thin lines should be one colour only.
11. Use overprint for black text on non-white background.
12. Jobs should not contain „composite black” for neither text nor graphics.
13. Every file can be preflighted before sending to production. We can provide our customers free PreFlighter software, which would check that the job is prepared correctly.
Most common errors we find:
-
no
fonts included
–
using low-resolution images (or unresolved OPI comments)
–
no
bleeds or incorrectly sized bleeds
–
RGB
colours, or colour definition other than CMYK/Pantone
-
composite black text or graphics
-
hairlines or other lines too thin to be consistently reproduced in printing.
How to deliver jobs to production:
- public FTP server (incoming PDF files are secured with passwords)- CD-R or DVD-R written using ISO format (PC)
