Abstract

A method for producing an ink-printed article with two different and disce gloss finishes by using inks with different drying times and then applying an acrylic coating to article covered with the inks prior to the complete drying of one of the inks but after the substantial drying of the other ink to produce an article where the surface of the article has at least two different and discrete finishes, wherein the glossier finish corresponds to the faster drying ink.

Claims

1. A method of making at least two different and discrete gloss finishes on the surface of a printed article by applying inks to the surface of an article comprising the steps of:

applying a first printing ink having a first drying time to a first portion of the surface of the article;

applying a second printing ink having a second drying time shorter than the first drying time of said first printing ink to a second portion of the surface of the article; and

then applying an acrylic coating to the first and second portions of the article covered with the first and second printing inks after both inks are sufficiently dry so as not to smear or smudge but before the first printing ink is dried and after the second printing ink has dried sufficiently so that the first portion of the surface of the article having the slower drying first printing ink dries with a gloss finish that is duller than the gloss finish of the second portion of the article having the faster drying second printing ink.

2. The method of claim 1 wherein the acrylic coating is applied after the second printing ink is completely dried.

3. The method of claim 1 wherein the acrylic coating is applied to the article before the the second printing ink is completely dried to thereby produce an article with different gloss finishes.

4. The method of claim 3 wherein the article with printing inks thereon is passed through an oven to heat the printing inks prior to coating the surface of the article with the acrylic resin.

5. The method of claim 4 wherein the article with the printing inks thereon is passed through chilling rollers to cool the article prior to coating the surface of the article with an acrylic resin.

6. A method of making at least two different and discrete gloss finishes on the surface of an article by applying inks with different drying rates to the surface of an article comprising the steps of:

applying a first printing ink having a first drying rate to a first portion of the surface of the article;

applying a second printing ink having a second drying rate to a second portion of the surface of the article, said second drying rate substantially faster than said first drying rate so that there is a post ink application period where the second printing ink is drier than the first printing ink but both of said printing inks are sufficiently dry so as not to smear or smudge; and

then during the post ink application period applying an acrylic coating to the first portion of the article covered with the first printing ink and to the second portion of the article covered with the second printing ink thereby causing the acrylic coating over the first portion of the surface of the article having the first printing ink to dry with a first gloss appearance and the acrylic coating over the second portion of the article having the second printing ink with the faster drying rate to dry with a second gloss appearance that is glossier than the first gloss appearance.

7. The method of making an article having a contiguous coating with at least two regions with a different gloss finish in the coating comprising:

applying a first printing ink having a first drying rate to a portion of the surface of a base member;

applying a second printing ink having a second drying rate faster than said first drying rate to a further portion of the surface of a base member;

drying said first printing ink and said second printing ink until both said first printing ink and said second printing ink are sufficiently dried so as not to run or smudge;

applying a clear see-through top coating to said first printing ink and said second printing ink; and

curing said clear see-through top coating when said first printing ink is in less of a cured state than said second printing ink to thereby produce a first light reflecting surface over said first printing ink and a second light reflecting surface over said second printing ink that is glossier than said first light reflecting surface so that a viewer perceives the surface of the article as having two distinct and discrete gloss finishes.

8. The method of claim 7 including adding tung oil to said first printing ink to retard the drying rate of said first printing ink.

9. The method of claim 7 including adding at least 8 percent by weight of tung oil to said first printing ink to retard the drying rate of said first printing ink.
