Principle of laser cutting after UV printing

 

“After UV printing, how do you align the position so that laser cutting can be done?”

It’s an easy story for those who know, but I also didn’t know how the two pieces of equipment work together, so I’ll explain.

I. “How do I cut accurately after printing when the equipment is not connected via USB?” _Principle of laser cutting after UV printing

 

While selling UV printers to overseas dealers, I occasionally saw Consburg and Zund cutters in dealer offices during business trips.

While watching them print with UV printers and cut accurately with cutters,

 

“But how do you cut accurately?”

“Read the black dots over there and cut according to the cutting file.”

“Oh, that’s right!”

 

There were a few times when I just answered like that and moved on, not because I was interested.

But I just couldn’t understand it.

‘If I UV print and move the printed material to the cutter, all the position values ​​are wrong. Even if I have a camera, how do I cut it?’

Since I didn’t know much about AI files,,

‘If I put the printed material on the cutter, does the camera automatically read it and just cut it?’

‘The UV printer and cutter aren’t even connected by USB or anything,,,,’

For over 10 years,, whenever I saw a cutter, I thought, ‘I should look into it,’ but when I left that place, I forgot about it again,

 

II. Instead of USB, there is a circle mark and a camera _Principle of laser cutting after UV printing

 

1. Linking two devices _Principle of laser cutting after UV printing

 

The UV Printer and Laser Cutter are not directly connected.

• The UV Printer prints,
• and Laser Cutter reads the position values ​​of the printed material with a camera and cuts only along the cutting line.

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

 

2. Role of crop mark in Ai file _Principle of laser cutting after UV printing

Since there should be both white and color in the AI ​​file, I understand the color layer and white layer,

and since there should be cutting, I think there should be cutting lines as well.

“Then why are there crop marks?”

 

The AI ​​file consists of a total of 4 layers, as shown in the figure below.

 

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 + white layer is included.

 

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

Includes Crop mark + Cutting line layer.

Only the crop mark layer is included in both the UV Printer printing file and the Laser cutting file.

Based on the crop mark, the printing surface and the cutting line are matched 1:1 at a certain interval.

In this way, all files are matched 1:1 based on the crop mark layer, so the location values ​​are correct.

 

3. Laser CCD cutting sequence _Principle of laser cutting 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 _Principle of laser cutting after UV printing

 

1. Things to check on UV Printer _Principle of laser cutting 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. Good to know about laser cutting machines _Principle of laser cutting after UV printing

 

Laser cutting machines also have mechanical errors because they move on the X and Y axes to cut.
The camera also has a tolerance, so you should take this into account.

Therefore, you can reduce the range of errors by putting in 5, 6, or even 8 crop marks rather than 4,
and of course, it is better to cut a small acrylic than a large one.

Don’t be too greedy, and make the acrylic size you print an appropriate size,
and since printing crop marks doesn’t excessively increase the printing time, we recommend putting in at least 5.

 

3 . The completed key ring _Principle of laser cutting after UV printing

 

“We have a laser cutter that we bought expensively in the past, but it didn’t have a dome mark function. Can’t we just align it well and proceed with the cutting?”

Actually, some people who know lasers well do it that way. However, they have a hard time.

What’s worse, those who bought cheap laser cutters without a crop cutting function…

“No matter how well you align it, it leans to one side at the end… Ah, I regret it. I should have bought a machine that cuts dome marks.”

 

If you are purchasing a new product, please purchase it with the crop cutting function included.

 

 

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.

Since words alone are not convincing, we are organizing all the troubleshooting DATA as follows.
