Printing a full black background with a desktop inkjet printer can prove challenging. Large amounts of concentrated black ink have a tendency to over-saturate the top-coating used on most glossy inkjet materials when printing with the default printer settings. Selecting the "Best" quality option will typically result in bolder colors, but also tends to exacerbate the over-saturation issue.
The biggest key to improving the print durability and reducing smearing and smudging is the paper type setting. The default paper type setting for the HP ENVY 4520 is Plain Paper. Plain Paper settings typically output a higher volume of ink since uncoated paper products are very absorbent and require more ink output to produce vibrant colors on that type of material. Using the Plain Paper setting on a glossy material may result in a more vibrant printed image, but it will likely also over-saturate the glossy top-coat - leading to a greater chance of encountering smearing issues.
Selecting the Other Photo Inkjet Papers setting is the best way to ensure that smearing won't be a problem. This setting will make sure that the correct amount of ink is being applied to the glossy top-coating in order to avoid smearing and smudging. As you mentioned in your post, you may see a slightly duller appearance for black backgrounds when compared directly to prints using the Plain Paper setting that is over-saturating the glossy top-coating. Unfortunately, this is simply a limitation of the printer model combined with the material type and design featuring a full black background.
We keep a wide variety of different inkjet and laser printer models on hand for testing purposes, including the HP ENVY 4520 that you're currently using. I spent some time this afternoon print testing black labels on the white gloss inkjet material in hopes of finding some possible suggestions to provide to you.
Here's what I found:
- Using the default Plain Paper setting will provide a truer black background color, but will also result in smearing no matter what.
- Using the Other Photo Inkjet Papers setting will result in print that cannot be smudged, with the faded black background that you reported in your post.
- Using the Other Photo Inkjet Papers setting and manually adjusting the quality setting to "Best" will provide a darker black background that cannot be smudged, but it still won't quite match the depth of the black color possible on the over-saturated Plain Paper prints that are prone to smearing and smudging.
If you've tried the combination of the Other Photo Inkjet Papers setting with the "Best" quality setting and are still not satisfied with the print quality, you could potentially use a clear protective spray like Krylon Preserve-It to "seal" the labels after printing with the Plain Paper setting. This should add durability to the print, while allowing you to maintain the darker black background achieved by over-saturating the material. You can view some tips on applying the Krylon Preserve-It spray in the article linked to below:
https://www.onlinelabels...ke-labels-waterproof.htmIt's important to note that the spray will not make the white gloss inkjet material "waterproof" as it's still a paper based material that isn't intended to hold up to consistent contact with moisture. It should dramatically improve the durability of the print though, and should also provide some protection from incidental contact with moisture.
If for any reason you decide you're unable to use the label material you've purchased we'll be happy to accept it back for a refund on any unused material. You can initiate a product return by visiting the link below:
