This page
is specially prepared to you so that you can know the benefits and
limitations of professional digital press so that you can
maximizing a higher quality of prints. At the same times, clearing
some mysteries of printing..
WHAT IS DIGITAL PRINTING?
Digital
printing uses computer technology to drive the printing devices to
produce color or black and white documents. Digital documents are
designed on computers, using layout software and electronic
content -- representing both text and images such as graphics and
photos. In this process, computers also manage the digital
printing workflow, from controlling jobs and equipment to billing
and accounting.
BENEFITs
Consistents
colour reproduction in the CMYK colour spectrum
Quick
turn around time
Economy
Variable
data printing (VDP) capabilities
We do not require colour
proof, what you see on the printout is what you getting. Our print
sample will be the final product.
NO
minimum qualities
No
setup time, setup fee
No
messy plates, films, etc..
Files
are printed immediately from the softcopy (ie. cd, dvd, memory
drives..)
LIMITATIONs
Although
our Xerox DocuColor Press is PANTONE certified, there are some
pantone colours that cannot be reproduced. They are namely
luminous and metallic colours
Patchiness
may be apparent in large chunks of single colour tone
Banding
may appear in gradients
Paper
sizes in digital printing remain limited. In fact, many output
devices have physical restrictions that prevent them from printing
to the papers edge. The maximum page size ranges super A3 or 12?x
18.?
No
textured paper

USE
PROPER RESOLUTION
Resolution measures how much detail an image or illustration has
and is measured in dots per inch (dpi). In digital printing,
recommended resolution for images is 300 dpi at 100 percent size.
By selecting this resolution, you can secure a high level of |
|
information to render, or digitally produce an image, yet still
keep the file size manageable. It is not advisable to work or save
your images in 300 ppi at 200 percent because they will have
visible defects such as pixelization (visible individual pixels)
or jaggies (lines shaped like a step).
IMAGE
RESOLUTION
The
sharpness of an image or illustration depends on the number of
pixels used to describe it. The 300 dpi image has great detail,
but at a price: file size. The 300 dpi image shows plenty of
detail while keeping the file size down. Images lower than 150 dpi
show signs of fuzziness and pixilation. Note that if you import an
image that is 300 dpi and enlarge it 200% you are in effect
reducing its resolution by half. Thus, a 300 dpi image would look
like the 150 dpi image here.
Digital printing handles type and line art differently. Files are
expressed in PostScript, digital shorthand that stores information
in coded instructions rather than a mosaic of pixels. PostScript
allows you to render files at the maximum resolution of the
printer, which ranges between 400?200 ppi, producing sharper type
and illustrations that are easily editable.

if you are using PDF creation software such as Distiller, make
sure that your PDF files are created with the "press optimized"
settings.
When it comes to imposition, please do not do the imposition for
us. Simply supply the artwork and set then to the correct size and
resolution (300 DPI/inch) + 5mm bleed all around.
Supply a hardcopy proof if possible if you are concerned about
colour matching. Note that we can print production proofs, at at
flat charge of SGD$10.00 per print. This will be refunded upon a
final production is awarded to DigiLab.
To enhance large areas of black, use rich black:
C - 40%
M - 20%
Y - 20%
K - 100%
if you intend to print spot colors, you may request our pantone
chart from us at SGD$30.00 per set
Avoid tints below 10%, and limit gradients to not exceeding 8
inches. With some colours there may be banding, so it helps to
introduce some Gaussian noise to hide any irregularities
such as lines or uneven density caused by the substrate or
printing process. However, best if background are photographic in
nature.
