If you’re considering upgrading to the latest aqueous ink printers from Canon, Epson or HP, consider no more. Reports from the field have shown that these next-generation models print up to twice as fast and use less ink than their predecessors.
They also use additional ink channels in the printing process, which increases the color gamut. As part of these expanded ink sets, all the latest printers now include Matte Black and Photo Black channels. While HP and Canon printers can switch from Matte Black to Photo Black on the fly, Epson printers require you to purge the line to switch inks, so keep that in mind as you switch between the two if you have an Epson printer.
Because of this expanded ink set, it’s necessary to pay close attention to the profile or media type being used, and to use a matte material profile/media type with matte materials, and a satin/luster or gloss material profile/media type with gloss materials. Note: If you’re using a RIP like Onyx, you’ll choose a media profile, which will determine which black ink is used. If you’re printing through the driver, you choose a profile as well, but it’s the media type that will choose the black ink channel that will be used.
Matte Black provides an image quality advantage as it yields much better density, which works extremely well on backlits. However, Matte Black ink is not compatible with all media. If you choose the wrong profile/media type, the Matte Black ink will wipe right off, even after the print is completely dry. This is especially true with media that has a microporous inkjet coating, such as LexJet 8 Mil ImagePro Gloss.
On the other hand, using Photo Black ink on a matte material will result in lower density in the dark areas and a more washed-out look, though Photo Black ink will have better dry times and durability, regardless of the material. Photo Black is more water-resistant and is best for unlaminated outdoor applications.
On large production runs, a lot of print shops use a standard generic profile/media type like Heavy Weight Coated, which is a bond paper profile that lays down less ink. If this profile/media type is used on gloss materials, it will activate the Matte Black channel, which is largely incompatible with gloss materials and will not absorb into these types of coatings.
A good generic profile/media type for matte materials is Heavy Weight Coated. A good one for gloss materials is Glossy Photo, which, like Heavy Weight Coated, uses less ink.
