8. Description of Primer functionality and limitations

 

“They say after UV printing, they use a camera to adjust the position and cut only the desired area… How does that work? I don’t understand.”

It’s easy for those who know, but even I, a UV printer salesman, didn’t know the exact mechanism, so I’ll explain it here.

 

I. “The equipment isn’t even connected, so how can I set the location?” _Camera cutting principle after UV printing

 

When I worked for a UV printer manufacturer, I did overseas sales.

Sometimes, at overseas dealer demo rooms, I saw Konsberg and Jund cutters cutting precisely along the UV printed surface.

I asked the dealer:

“But how do they cut so accurately?”

“They read the black circle and cut according to the cutting file.”

 

I wasn’t interested, so I didn’t ask any further questions, and I didn’t understand what he meant.

“After UV printing, and move the printed material to the cutter, the positioning values ​​are off. Even with a camera, how did it get the exact position?”

 

Because I didn’t know AI files,

‘When the printed material placed on the cutter, does the camera automatically read it and cut it?”

“The UV printer and cutter aren’t even connected via USB or anything…”

For over 10 years, I’d see a cutter and think, ‘I’ll check it out,’ but then forget about it the moment I left.

 

II. How the cutter recognizes the print position _Camera cutting principle after UV printing

1. Linking two devices _Camera cutting principle after UV printing

 

The UV printer and laser cutter are not directly connected.

• The UV printer simply prints,
• while the laser cutter uses a camera to read the printed material’s position and moves according to the AI ​​file to cut.

The two are connected by the crop marks layer in the AI ​​file and the camera.

 

2. Role of crop mark in Ai file _Camera cutting principle after UV printing

Since the AI ​​file requires both white and color, I understand the need for a color layer and a white layer.

Since cutting is also required, I also understand the need for a cutting layer with only the cutting lines drawn.

 

An additional crop marks layer is needed to read the camera position and cut along the cutting lines.

In other words, for camera cutting after UV printing in an AI file, a registration mark layer is required in addition to the print and cutting files.

As shown below, for camera cutting after Color & white printing, the AI ​​file consists of four layers.

 

The image below shows only the layers that need to be printed with a UV printer.

Only the cutting line layer is excluded, and the crop mark, color, and Color & white layers are included.

 

The image below shows only the layers used when cutting with a laser cutting machine.

Includes the Crop Mark + Cutting Line layers.

 

Only the crop mark layer is included in both the UV printer print file and the laser cutting file.

The print surface and cutting line are aligned 1:1, with a certain gap between them, based on the crop mark.

The AI ​​file explanation alone is not fully comprehensible. The actual cutting execution sequence below will help you understand.

3. Laser camera cutting _Camera cutting principle after UV printing

The operation sequence of the camera-equipped laser cutting equipment is as follows:

• Place the printed material on the plate to be cut.
• Load the file with the crop mark + cutting line into the program.
• Select one of the four circles (crop marks) on the printed material and position it so that the camera can see it.
• Using the function in the program, recognize one circle that is shown to the camera.
• Once one circle is recognized, use the same automatic circle recognition function in the program to recognize the remaining three.
• Once the four circles are recognized, press the “Start” button to proceed with cutting.
• When the “Start” button is pressed, the laser cutting equipment does not cut immediately, but moves the X and Y axes until the camera recognizes all four crop marks,
• and then proceeds with cutting according to the cutting line in the file.

By reading the four Crop marks on the printed material with the CCD camera,

• Laser recognizes the exact location of the UV Printer printed material placed on the laser cutter,
• and from then on, the laser cutter will only cut along the cutting lines in the file.

“So, even if there are only crop marks on the unprinted acrylic, will it cut along the cutting lines, the red lines in the picture above?”

“That’s right. If the laser properly recognizes the Crop marks, it will start cutting along the cutting lines in the file, regardless of whether there is an image on the acrylic.”

III. Some details _Camera cutting principle after UV printing

 

1. UV Printer _Camera cutting principle after UV printing

I told you that UV Printer only prints, and Laser only cuts according to the cutting file.

 

“If there is a slight error in the printing size printed by UV Printer,”

 

If the crop mark in the printed image is within the allowable error range, the laser cutter will successfully complete the process of reading the crop mark and proceed with cutting according to the cutting file.

In other words, the cutter ignores the printed size error and proceeds with cutting only according to the cutting file.

Then, some products have the same margin based on the image, but some images have the margins concentrated on one side.

For this reason, I strongly recommend that you perform [Size Correction] on the UV Printer.

2. Laser cutting machine _Camera cutting principle after UV printing

Laser cutters also have mechanical errors because they move along the X and Y axes to cut.
Camera tolerances also apply, so this should be taken into account.

For this reason, I’ve seen some users use five or even eight crop marks instead of four.
More crop marks reduce the margin of error, and
cutting smaller acrylic pieces has a smaller margin of error than cutting larger ones.

3. The completed key ring _Camera cutting principle after UV printing

 

“We previously purchased an expensive laser cutter, but it didn’t have a registration mark feature. Why can’t we just align it properly and start cutting?”

Some people cut without a CCD camera, but after a few tries, they find, “No matter how well I align it, it always drifts to one side at the end…”

If you’re buying a new machine, I recommend including the simultaneous cutting feature.

IV. This is how ARTJET supports our customers.

One thing I feel while selling and maintaining ARTJET UV Printers for 5 years is that the next most important thing after product stability is Troubleshooting DATA.

All products have problems, whether they are actual equipment problems or consumer errors, and product stability is how easily and quickly you solve those problems.

We are organizing all the troubleshooting DATA as follows.
