are these labels available in smaller quantities per roll? ex:155 labels per roll.

The 4" x 3" thermal labels are only available at 500 labels per roll for the 1" core. We can customize sizes and shapes, but not the number of labels per roll at this time.

What is the mil of the label material itself? Without backer. Thanks.

The Standard White Direct Thermal (DT) material has a facstock thickness of 3.4 mil +/- 10%.

What machine do you use to print on these labels? Do you need ribbon?

The RL783 features 4" x 3" labels on a 1" core with a 4" outer diameter and 0.125" spacing between labels. This product can be ordered in direct thermal and thermal transfer (ribbon required) materials. We've successfully tested with Zebra brand printer models. But if using a different brand printer, you'll want to check the printer's specifications to ensure it can take a roll this size and offers gap sensing.

does this work well in -20 degrees Fahrenheit temps

The Weatherproof Direct Thermal (DW) material can be applied to a surface with a temperature as low as -8°F. Once applied it can withstand temperatures from -65°F to 147°F.

What is the material ?

The RL783DW is produced on our Weatherproof Direct Thermal (DW) which is a thermal polypropylene material.

Hi, is this label resistant to sunlight? if not, do you have another direct thermal label that is resistant to sunlight and can you leave it outdoors? Thanks, Jefferson

Our Weatherproof Direct Thermal (DW) material is a water resistant label stock with a permanent adhesive that's recommended for short term use. The plastic film material will ensure durability in direct contact with moisture, but if the printed labels are exposed consistently to direct light, heat, or chemicals the label could potentially fade or darken over time. If you have access to a thermal transfer printer, you may want to consider the Weatherproof Thermal Transfer (TW) material. This is ideal for long term use and would be a more durable option.

I currently use this white label. I am looking to get this label in Fluorescent Orange as well. Is that possible?

At this time we do not offer colored thermal materials. We do, however, offer colored materials on 8.5" x 11" and 8.5" x 14" sheets. You can review our available sheeted materials at the link below. https://www.onlinelabels.com/browse_material.aspx

What printers and model do these labels work with?

Our RL783DW features 4" x 3" weatherproof direct thermal labels on a 1" core with a 4" outer diameter which has been tested on Zebra brand direct thermal printers. If you're using another brand thermal printer, you'll want to verify the printer's specifications. Please note that these thermal products are not compatible with Brother or DYMO brand printers. However, we do offer a separate line of DYMO compatible products below: https://www.onlinelabels.com/comparable/dy-labelsb

The Standard White Direct Thermal is a paper-based material with a matte finish.

Can you use these in zebra printers?

RL783DT is a 4" x 3" direct thermal label on a 1" Core with a 4" outer diameter. As long as the Zebra printer model you are using is direct thermal and allows for these specifications, it should work well. If you'd like to verify the compatibility, please contact Customer Support at 888-575-2235 with your printer model.
