Once all is double checked the machine can be turned ON
Understanding how the machine cuts to get a good result
To get the machine to work correctly you first need to understand the cutting operation / measurements and set-
tings.
Definition of the cutting process
- The uncut sheet
The machine calculates and works from a unique reference point which is the back edge left side corner of the
paper
Known as the
origin 0/0, all other things are referenced to this point.
- There are 2 cut axis
X direction
means length-ways positioned cross cuts or cross creases or strike perfs
Y direction means cross positioned slits
- Mark reader
There is a mark reader that will re calculate the cut positions according to the movement or drift of the printed mark
as compared to the origin point in both axis.
If the mark is not positioned and printed correctly the cut positions will be incorrect.
- Laying out the cuts
If you want to layout a sheet and then cut it accurately you need to know certain reference points as compared to
the origin see the template.
In the
X direction from left to right in order
- The total sheet length
- The lead edge first cut
- The card length
- The gutter cut length between cards , if required
- The nr of repeat card cuts that need to be made
- The remaining trailing edge trim cut
All the amounts have to be within the template spec and add up exactly to the full length of the sheet
The length of the sheet = lead trim + (card length x n) + (gutter cuts x n) + tail edge trim.
In the Y direction from back to front in order
- The total sheet width
- The rear bleed trim
- The card width
- The gutter width
- The total nr of cards and gutters required
(usually max 3 rows but can be up to 4 rows if no gutter slits required)
- The side trim bleed width
Note side trims are always deflected to the waste bin unless the heads are set at home position
Sheet width = front and back side trims + (card width x n) + (gutter strips x n)
Math
It sounds obvious but the numbers need to add up....
A precision
steel rule with 0.5 mm increments is a must to set these jobs.
