Trotec laser machines are the optimum tool for processing paper and card. You can refine greeting cards, book covers, table decorations or packaging with a detailed engraving or filigree pattern using a laser machine. Here are some helpful tips regarding the laser cutting and laser engraving of paper.
The engraving results depend on different factors. Dark and light laser engraving is possible even with dyed-through paper types. Therefore a colour change from dark to white can be achieved with a very low power output. You can also create a dark haptic engraving by using a higher power output. In the case of paper types with two or more layers, the cover layer is removed and the second colour is then visible.
Below is a summary of techniques for paper processing, including examples of laser parameters.
There are infinite types of paper and card, so it is important to know the properties of the material used. You can find the parameters for laser processing easily with the help of the test matrix. This will help you quickly determine different effects of the laser engraving.
Tip: Fine paper types produced with two different-coloured layers can create amazing, contrast-rich engraving results.
When paper laser cutting at high speed the removed material will evaporate as smoke. The smoke transports the heat away from the paper, so the material is only slightly thermally marked. With optimum parameters, Air Assist and Table Exhaust, the material can be processed smoke-free without burnt edges even with the finest contours.
For paper laser cutting and engraving, we recommend using a 1.5" lens because larger optics are not necessary for the minimal thickness of the paper. The 1.5” lens is also best suited for filigree laser engravings, as fine graphics can be represented in a detailed manner.
You can increase the success of your engraving by selecting the right table. However when you are laser engraving paper, you only need a vacuum table, which provides optimum vacuum if you cover the remaining work surface.
When you are ready to laser cut your paper, we recommend using a comb cutting support, best used in combination with a vacuum table. This helps prevent unattractive cut marks on your vacuum table with the honeycomb cutting support. It also significantly reduces supporting surface of the material and minimises residue on the back side of the material.
Tip: We recommend covering the processing surface completely with a cover material, so that you are working with full vacuum and that the paper remains flat on the table. Printer paper is sufficient for this.
The resolution always depends on your application. When you want to process "normal" engraving jobs, use "500dpi resolution" and "Air Assist On". This will combine very good quality with a fast working speed. You can adjust both parameters in JobControl® via the material database.
For photo engravings on paper, we recommend reducing the resolution to 250-333 dpi, as the screen points appear slightly enlarged on paper and would overlap if a higher resolution was used.
If you only want to cut the paper, set the resolution to 1000dpi.
Cut incredible details from printed material with the Trotec software, JobControl® Vision. A camera on the working head of the laser reads the printed registration marks. Distortions in the print area are detected and compensated, meaning the material is precisely cut. Production times are accelerated and cost-intensive incorrect cuttings are avoided.
