Which printing press for best quality or price?
If you are like most people, then the answer is yes. The answer to the
question of which printing press is an important one, as the wrong
printing press can
increase your price, as well as potentially diminish the quality of your
full
color printing.
- If pricing is your most important goal, then the correct printing press
size and type of printing press becomes important for you. What are these
printing press types and sizes?
- The Docutech printing press: This is built for short run manuals
or booklets of many pages. It prints from your disk directly onto the paper,
using toner and not ink. It has a relatively high line screen and the end
result will have a dry look (due to the toner) unlike ink, which has a wet
look. It prices better than ink printing for runs up to a couple of
thousand books. It is the industry standard for book
printing under 1,000 books.
- The Docucolor printing press: The sister to the Docutech and
built for color printing. When you require
full color that has many
pages and is a short run quantity, this offers the same benefits as the
Docutech: better per unit pricing for short run full color printing.
- The Sheet Fed printing press: The sheet fed printing press
provides you with
a better quality (but not overly noticeable beyond the dry look of the
Docucolor printing press) full color printing product and it's benefits lie
within the varying printing machine sizes. The smallest sized ink full color
machine is the Heidelberg "GTO", which runs an average 13.5 x 19
printing form and thereby not beneficial for more than a four page document. For short run
color printing this is ideal, as you get the
best quality printing at short run print prices.
- Following the small "GTO" press, the next step up in press
sizing is the 28" and this usually comes with a five plate
configuration; allowing you to print in full color plus one pantone or spot
varnish in addition to the process full color printing.
- The big boy of the sheet fed machines is the 40" six color.
While the 28" is configured to print up to a 12 page booklet, the 40"
is built to print 16 pages signatures (a sixteen page booklet of a standard
letter sized page). The bottom line: the larger the page count, the bigger
the machine required for optimal print efficiency: Efficiency equals price
and quality. This printing
press is also the one generally used for the "gang run" process.
For example, it can run eight different flyers for eight different customers
on one sheet and thereby saving each of the eight from having to pay for a
custom run of only a few thousand flyers.
- The web printing press: The web machine is a rotary one, which utilizes roll paper rather than large, or small,
"parent" sheets of paper which are pulled through one at a time.
The rolls shoot through the web printing presses at very high speeds, with the
newest versions running so fast it is mind numbing. Sometimes, should you be
at a run check, you will see
the pressman actually running between stations on these ultra high speed
machines, making adjustments. This is because on these machines the paper
consumption is so fast, that any errors cause great waste
of paper. Paper is usually about half the cost of the job, so waste is
crucial.
- There are two basic types of the web machines: The Heat-set and
Cold-set. The main difference is that the Heat-set web has heaters which dry
the ink, thus allowing it to run coated stocks (gloss book, dull book, etc.)
The Cold-set webs can only run offset-un coated stocks and newsprint.
The secondary consideration between using a Heat-set or a Cold-set web is the line-screen.
The Heat-set webs tend to be newer and therefore having a higher
line-screen (between 133-175). The Cold-set, having
anywhere from 85-150 line-screen, with larger dots and less detail.
- The next difference in the web style is size. Here, once again,
size matters. The smallest rotary machine is the label web
and these are only several inches wide. Forms presses and the
"Didde" is the next step up as both generally run a 4 page
configuration. These are also referred to as "quarter webs".
Then there is the "Half Web ", which somehow manages to not
only run the 1/2 form of the 8 page signature, but also is built to run a 12
page signature. This then brings us to the "Full Web", which
is built to run a 16 page signature as well as the full web that can
run "double sixteen's", thereby running 32 page
signatures.
