Question- When using the ULTRA spray on stainless steel tags we are getting spotty results. Not solid black.  I have a 25 watt universal M300 laser. Experiencing faintness in some areas of the tag.   Our settings are power 100 and speed of 20. PPI of 600.

Answer-  https://jorlink.com/laser-supplies/cermarkthermark/thermark-how-to-use/laser-settings-chart      .

These are suggested starting settings.   All of the laser spray products will require some experimenting to perfect. Even two lasers that are the same brand, model and power will be different. Over time the laser tube will change in power and that will effect the results. More power does NOT mean better results. There is a sweet spot you'll want to find.

Question- What is the main difference between LMC 6000 and LCM 6044P?

Answer- LMC6044P product can mark a range of glass and ceramic substrates. It has previously been used to mark many different types of glass in industrial applications such as vehicle windshields, laboratory instruments, plate glass, and glass ampules. It can also be used for decorative work on bottles, wine glasses, and awards. Additionally, it has found uses on ceramic products such as porcelain sanitary ware, electronic substrates, and for decorating walls and floor tiles. In another way, the Lmm6000 is designed for metals is recommended for creating black marks on a variety of metals such as Stainless Steel, Bright Annealed Chrome, Plating Titanium Galvanized, Steel Nickel Plating, Brass Aluminum Gold, Plating, Copper, Pewter, and Silver Plating.

Question- I'm needing to engrave on some award medals for a school. I've got some of your Cermark 6000 and Cermark Black Laser Marking spray - I'm trying to figure out if I can use it to laser engrave on an award medallion that is made of zinc alloy?

Answer- About your question: Fiber lasers are the most efficient at generating permanent & high-contrast identifiers on these materials. You can etch barcodes, data matrix codes, QR codes, serial numbers, logos and even more on all types of zinc parts. Cermark is not the answer to engrave zinc alloys with CO2 Laser. Even if you get it to work the next item from the same product line may well have a totally different composition and not work. Cermark is to engrave all kind of metals but not zinc alloy.

Question-  What other colors for metal are currently available?

Answer- Currently we offer a black LMM-6000 & LMM-14 on metal substrates. CerMark also offers LMM-6150 Pearl (off white) and LMM-6151 Copper which will mark on stainless steel, Black Oxide and Black Parkerized metals widely used for firearms and knives and a variety of tools. Contact us for more information.

Question- Can I get blacker marks with a thicker coat of LMM-6000 & LMM-14?

Answer- No. Additional LMM-6000 & LMM-14 film thickness will only result in more power being needed to make a mark; it will not make the marks any darker.
