Foil look printing technique
View Patent ↗A process of manufacturing envelopes and a product manufactured in accordance with such process is disclosed. The process requires printing of an ink design on an envelope, coating of the ink design with a varnish and subsequently embossing the combined ink and varnish design so that a foil look is obtained on the envelope.
1. A process of manufacturing envelopes comprising:
feeding a web of paper into an envelope manufacturing machine;
printing a design made of ink on said paper;
printing a varnish coating only on said design;
embossing said paper at said design after the varnish coating has been printed thereon so that said design is raised above nonembossed areas of said paper; and
folding and gluing said paper to form an envelope.
2. The process of claim 1 further comprising drying said varnish prior to embossing said paper.
3. The process of claim 1 wherein said folding and gluing of said paper is performed after said printing and embossing steps.
4. The process of claim 1 wherein said folding and gluing of said paper is performed prior to said printing and embossing steps.
5. The process of claim 1 wherein said step of printing ink comprises a flexographic printing technique.
6. The process of claim 1 further comprising cutting said web of paper prior to certain of said folding and gluing steps.
7. The process of claim 1 wherein said ink comprises metallic ink so that a foil look is obtained after said embossing step is performed.
8. The process of claim 1 wherein said ink comprises multiple colors arranged adjacent to each other within said design so that a multi-colored or rainbow appearance is obtained.
9. A process of manufacturing envelopes comprising:
providing an envelope manufacturing machine including a paper feeding section, a printing section, a drying section, an embossing section, a cutting section, a folding section and a gluing section;
feeding a web of paper through said paper feeding section;
printing a design made of metallic ink at a selected area on said paper;
printing a varnish coating only on said design; and
embossing said design at the selected area after the varnish coating has been printed thereon so that said design is raised above nonembossed areas of said paper whereby said design obtains a foil look.
10. The process of claim 9 wherein said metallic ink includes a color selected from the group consisting of gold, silver and bronze.
11. The process of claim 9 further comprising the step of drying said metallic ink as said paper passes through said drying section of said envelope manufacturing machine.
12. The process of claim 9 further comprising the step of drying said varnish as said paper passes through said drying section of said envelope manufacturing machine.
13. The process of claim 12 further comprising cutting, folding and gluing preselected areas of said paper after completion of said printing and embossing steps.
14. The process of claim 12 further comprising cutting, folding and gluing selected areas of said paper prior to completion of at least one of said printing and embossing steps.
15. The process of claim 9 wherein printing of said metallic ink is performed using a flexographic printing technique.
16. The process of claim 9 wherein said design comprises selected letters or numbers.
