Rotogravure Printing Requirements
The following specification has been designed to assist with rotogravure
printing prepress
and to minimize time loss/additional costing.
- Printing process: - rotogravure. Maximum 8 colours, including over
lacquers, coatings etc.
- Print tolerances. – 0.1mm to 0.2mm spreads and tucks.
i.e. to counteract shift due to print process or materials.
Avoid using two or more colors to form too thin or small text,
dots, lines, dashes, etc
- Leave clear track for registration mark.
- Barcode: reduce to 85% as a minimum scale.
- True color indicators/color standards, must be supplied (PMS number or
color sample).
- Artwork to be supplied as: (1)Adobe Illustrator : _.ai/_.eps + (2)Adobe
Photoshop : _.psd
(1) Adobe Illustrator : _.ai/_.eps (or FREEHAND, CorelDraw, etc.)
a) Create sophisticated vector graphics and text in
Illustrator.
b) Place the Photoshop images(.psd, .eps, .tif, .bmp,
etc) in Illustrator (links).
c) Create outlines for all text objects in
Illustrator.
(2) Adobe Photoshop : _.psd
a) Create and enhance images in Photoshop.
b) Create layers in any image and manage them in
Photoshop.
c) Place the Photoshop images (.psd, .eps, .tif, .bmp,
etc) in Illustrator (links).
d) Please attach all the _.psd files with all layers
created in Photoshop.
Do Not Flatten Images (Keep All Original Layers) & Save
as a _.psd file.
(Even if you have placed the images in Illustrator and save as a _.ai
file)
e) The _.psd files with all layers are very important
to rotogravure printing prepress.
f) The resolution of photographic image files must be
no less than 350dpi.
g) Create the images with CMYK channels (RGB channels
are not good for separation.)
h) Create the SPOT COLOR channels with PMS No. if you
would like to use PMS colors.
- Identify & show coverage of each color, specially the “PMS colors”, “white
color” &“transparent”.
- Play it safe and burn two copies of the artwork (above) onto a CD…we will
send one to the plant and the other we will use for inspection and Quality
checks internally.
- Play it safe and print out the artwork and send hard copies with the CDs.
Item 6 is the most important.
