Outdoor Eco Solvent Ink 1 Litre Black Oil Based Ink

A1:This ink is a red based on magenta (M) but with higher saturation. Visually, it appears redder, richer, and slightly cooler than the standard magenta used in conventional CMYK printing. If you replace the magenta (M) channel in your printer with this ink, solid red areas will look brighter and more accurate. Simply put, standard magenta tends to resemble a “pinkish” tone, while this red is closer to a “true flag red.”

A2:Using this ink alone makes it difficult to precisely match a specific PANTONE® color. The professional approach is to replace the printer’s magenta (M) channel with this ink and then fine-tune the CMYK mixing ratios to approach the target color. We strongly recommend conducting print tests in advance. You may contact our technical support team to request test files based on international standard color charts. Printing these files on your equipment and commonly used media, then comparing them with color references, is the most direct way to understand the achievable color gamut.

A3:This is usually related to the ink absorption uniformity of the media and the printer’s pass settings. Red pigments are highly concentrated and more sensitive to subtle differences in media coatings. If this occurs, try the following:

Increase print quality: Change the print mode from “Production” to “Quality” in the printer driver to increase the number of passes.

Check the media: Ensure you are using mild-solvent–compatible media with a uniform coating.

Unidirectional printing: For large-format prints, enabling unidirectional printing can improve uniformity, although it reduces speed.

A4:Yes. Under UV exposure, the molecular structure of red dyes is generally less stable, and traditional inks tend to fade toward pink or orange first. To address this, our formulation includes additional UV absorbers and stabilizers specifically targeting the red spectrum, helping to slow down this process. However, no dye is completely fade-proof. In environments with intense sunlight exposure, it is still reasonable to inspect outdoor graphics—especially red areas—every 1–2 years as part of normal maintenance.

A5:Thanks to its accurate red hue, this ink produces clean results when overprinted with cyan (to create purple) or yellow (to create orange). A practical tip is to slightly reduce the percentage of cyan in overprinted areas when preparing your artwork in the RIP or design software. This helps achieve a clearer, brighter purple and avoids a “muddy” or grayish appearance caused by excessive red–blue overlap. Exact values should be fine-tuned through testing based on your specific design.

A6:This is not just an impression. In many commercial advertising and promotional designs, red is often used as a dominant or attention-grabbing color (such as in promotional banners and warning signs), resulting in higher actual consumption compared to cyan or yellow. We recommend calculating ink usage in advance and preparing sufficient stock when handling large orders dominated by red tones, to avoid interruptions during production.
