I'm sorry to hear about the issues you're experiencing and I'll be happy to assist however I can.
We've extensively tested our weatherproof polyester material using a wide range of laser printers, including a few different HP Color LaserJet Pro models. I haven't had an opportunity to use the Color LaserJet Pro M454dw but the material was tested with the Color LaserJet Pro M452dn, which should be a very similar printer model in terms of functionality and print quality. I typically had my best results using the default quality setting with one of the heavier weight glossy photo settings. On my printer model the setting is listed as HP Color Laser Photo Glossy 220g. If this exact setting isn't available on your printer model I'd look for the one that comes closest to that type of description. Some trial and error may be necessary to dial in the best settings for your artwork, but those are the options that worked best for me.
If you're not seeing improvements to the print quality after adjusting the material type and quality settings there are a couple different maintenance options that will potentially improve print quality as well.
- Try running a cleaning page from the LCD screen on the printer model itself first. This will ensure that there's no debris or dust contributing to print quality issues moving forward.
- Check to ensure that the EconoMode setting on your printer is disabled
- Calibrate the printer from the LCD screen on the printer. Color calibration optimizes print quality and can help resolve problems related to blurry graphics, shadows, misaligned colors and other print quality issues.
- Try running the material from a different tray if your printer model has multiple trays
Printing onto a polyester film surface is a bit more demanding compared to plain copy paper. It's possible that some of these maintenance settings may be necessary to get the best results on the weatherproof polyester material.
Regarding the adhesive issues, are the labels being applied before or after the roller bottles are filled with the essential oils? Is there any possibility that oil residue is on the surface of the bottles? That would definitely run the risk of potentially degrading the adhesive quality in water. We've adhesive tested on a wide range of container and surface types and have typically seen excellent results in direct contact with moisture, even when submerged in water. We do have a label application guide available at the link below that provides some useful tips for improving the adhesion of your labels:
https://www.onlinelabels.com/articles/how-to-apply-labelsThe two most important tips referenced in this guide are:
- Ensuring that the surface of the container is clean. Debris, dust, or residue of any kind can potentially compromise the strength of the adhesive.
- When applying the labels, place the center down of the label down first and then apply even pressure outward. This will reduce surface tension, which can be a major factor in adhesive issues.
If you've tried these suggestions and are still experiencing issues then you may want to consider trying our weatherproof vinyl material. This material features a more aggressive adhesive that was designed to withstand the rigors of drum labeling and marine applications. You can view the product at the link below:
