Printing technology
As we all know, there are 125 variables that need to be controlled
in every lithographic printing machine, so it is difficult to
achieve the goal of keeping the consistency of business card
printing in Shanghai. A prepress expert once told me that they can
produce digital printing plates with errors within 0.5% under the
constantly changing environment of prepress workshop. Why we can't
do this is a complicated problem, but we can better manage the
printing press by adhering to the best practices and controlling
the workflow.

In order to avoid these problems, printing machine operators must
ensure the cleanness, ink absorption and softness of the cylinder.
I might read the hardness requirements of each cylinder put forward
by the printing press manufacturer. Some manufacturers may put
forward different hardness requirements for cylinders according to
their functions and their positions on the printing press, while
some manufacturers may provide users with a hardness value suitable
for all cylinders. Now, you must choose an appropriate hardness
value fo
When exposed to ultraviolet light or in an environment with high
temperature and easy oxidation, the drum will become hard.
Therefore, it is best to store the rollers in a dark place and keep
them away from heat sources and electric motors.r your printing
cylinder, and try to keep this value.
To keep the cylinders of printing presses soft, it is best to clean
them once a week with decalcified solution or hot water containing
15% vinegar. In addition, every weekend, the operator should
thoroughly clean the roller with ink roller cleaner, and wash the
roller again on Monday morning. If possible, try to avoid using
chemicals on the roller, and never use steel pads. In an ideal
situation, it is best to remove all the cylinders on the printing
press for manual cleaning every other quarter, and at the same
time, clean the support and frame of the printing press. This is an
arduous task, but as long as you work hard, you can see the
disappearance of stains and the improvement of printing quality.

What are the paper sizes of A3/A4/A5?
A3/A4/A5 refers to the size specification of paper, which means
that after the paper is made, it is trimmed and trimmed to a
certain size. In the past, the size of paper was expressed by how
many "sheets" (such as 8 sheets or 16 sheets, etc.). Now, I adopt
international standards, which stipulate that A0, A1, A2, ... and
other marks are used to express the format specifications of paper.
In our daily life, A4 copy paper, 8K paper refers to these sizes,
namely A4 paper (16K paper) size is 297mm×210mm, and 32K notebook
(A5 notebook) size is 21cm × 14.8cm.
The current format size is mainly a series of specifications, which
are as follows:
A2 | (4 open) | 594mm×420mm； |
A3 | (8 open) | 420mm×297mm； |
A4 | (16 open) | 297mm×210mm； |
| A5 | (32 open) | 210mm× 148mm； |
| A6 | (64 open) | 144mm×105mm； |
The size of paper printed here is different from that of
international standard paper. There are several paper sizes
commonly used for printing here:
A2 | (more 4 open) | 420mmx580mm |
| A3 | (more 8 open) | 285mmx420mm |
| A4 | (more 16 open) | 210mmx285mm |
| A5 | (more 32 open) | 210mmx140mm |
| A6 | (more 64 open) | 140mmx100mm |
