Abstract
The invention discloses a kind of offset press and realize the printing process of frosted finish effect, offset printing PS plate print couple is used first to print First frosted UV base oil, then on offset press glazing seat, print second UV face oil in soft version mode, after after UV solidifies, form frosted ink effect;Base oil dough-making powder oil usage ratio is 1:1.1 ~ 1:1.5.Pack now the universal group technology of product more in the case of, the present invention is a kind of manageable mode of production of improving production efficiency, in batches effect.
Description
Technical field
The present invention relates to a kind of frosted finish effect printing process.
Background technology
Existing print product frosted finish effect generally uses silk-screen or single recessed realizes, but usual silk screen printing process is inefficient, and cost of labor is high, and single recessed in plate-making, cost is high and in effect reduction difficulty bigger.
Chinese patent (CN 1709707 A) discloses a kind of offset printing frosting technology, and including three steps: 1, printing ground floor base oil is the most UV radiation curing；2, printing second layer base oil is the most UV radiation curing；3, printing surface oil also makes 5 oil and base oil reaction form imitative frosted finish effect with ultraviolet irradiation.But the method needs to carry out 3 printings, and finish printing every time be required for UV radiation curing.Not only operation is more, and the granular sensation formed is not the strongest.
Summary of the invention
The technical problem to be solved in the present invention: imitate, for existing offset printing, the more problem of operation that frosting technology exists, it is provided that a kind of new offset printing frosted method.
Technical solution of the present invention:
A kind of offset press realizes the printing process of frosted finish effect, it is characterized in that: use offset printing PS plate print couple first to print First frosted UV base oil, then on offset press glazing seat, print second UV face oil in soft version mode, after after UV solidifies, form frosted ink effect;Base oil dough-making powder oil usage ratio is 1:1.1 ~ 1:1.5.
The composition of UV base oil is as follows according to mass percent: polyester chloride 40-50%, epoxy acrylic resin 10-13%, polyester 22-28%, photosensitizer 3-5%, polymerization inhibitor 0.2%, silica sand powder 2-10%, wax powder 2-8%, superfine talcum powder 4-8%, organosilicon auxiliary agent 4-8%；The composition of UV face oil is as follows according to mass percent: epoxy acrylic resin 22-31%, polyurethane acrylic resin 8-16%, acrylic monomers 48-52%, photosensitizer 10-12%, polymerization inhibitor 0.1%, and organosilicon auxiliary agent 1-2% shrinks auxiliary agent 0.5-2%.
Glazing seat uses flexible resin plates, uses chambered doctor blade to coordinate the mode inking of anilox roll, and anilox roll designs in the range of 80-120 line/cm.
The cissing that resin plate reduces 0.2-0.4mm in offset printing file basis surrounding processes.
Resin plate uses the resin plate with aluminum base basis.
The method have the benefit that
Present invention offset printing PS plate print couple prints First frosted UV base oil, second UV face oil is printed in offset press glazing seat soft version mode, produce contractive effect because of the reason of surface energy after being designed two groups of ink formulations covering upper first group of base oil so that second group of face oil, and add the sand sense effect of the sand grains composition simulation frosted ink of certain particle diameter in First base oil.Two groups of ink form frosted ink effect after UV solidifies.
Pack now the universal group technology of product more in the case of, the present invention is a kind of manageable mode of production of improving production efficiency, in batches effect.
Detailed description of the invention:
The composition of embodiment one: UV base oil is as follows according to mass percent: polyester chloride 50%, epoxy acrylic resin 10%, polyester 24.8%, photosensitizer 3%, polymerization inhibitor 0.2%, silica sand powder 2%, wax powder 2%, superfine talcum powder 4%, organosilicon auxiliary agent 4%；The composition of UV face oil is as follows according to mass percent: epoxy acrylic resin 30%, polyurethane acrylic resin 14%, acrylic monomers 43%, photosensitizer 10%, polymerization inhibitor 0.1%, and organosilicon auxiliary agent 1.5% shrinks auxiliary agent 1.4%.Base oil dough-making powder oil usage ratio is 1:1.1.
Step one, uses offset printing PS plate print couple in printed on paper First frosted UV base oil.
Step 2, prints second UV face oil in soft version mode on offset press glazing seat.Glazing seat needs to make the flexible resin plates of corresponding document, glazing seat uses chambered doctor blade to coordinate the mode inking of anilox roll, the generally anilox roll that needs depending on sand sense needs design in the range of 80-120 line/cm, resin plate is that flexible fat composition needs the cissing reducing 0.2-0.4mm in offset printing file basis surrounding to process because of surface, to ensure that face oil mates with the size of base oil, the resin plate for needing the picture and text of precise restoration to be used preferably uses the resin plate with aluminum base basis.
Step 3, forms frosted ink effect after UV solidification.
The composition of embodiment two: UV base oil is as follows according to mass percent: polyester chloride 44%, epoxy acrylic resin 11%, polyester 23%, photosensitizer 3%, polymerization inhibitor 0.2%, silica sand powder 5%, wax powder 4.8%, superfine talcum powder 4%, organosilicon auxiliary agent 5%；The composition of UV face oil is as follows according to mass percent: epoxy acrylic resin 25%, polyurethane acrylic resin 12%, acrylic monomers 50%, photosensitizer 10%, polymerization inhibitor 0.1%, and organosilicon auxiliary agent 1.9% shrinks auxiliary agent 1%..Base oil dough-making powder oil usage ratio is 1:1.3.
Step one, uses offset printing PS plate print couple in printed on paper First frosted UV base oil.
Step 2, prints second UV face oil in soft version mode on offset press glazing seat.Glazing seat needs to make the flexible resin plates of corresponding document, glazing seat uses chambered doctor blade to coordinate the mode inking of anilox roll, the generally anilox roll that needs depending on sand sense needs design in the range of 80-120 line/cm, resin plate is that flexible fat composition needs the cissing reducing 0.2-0.4mm in offset printing file basis surrounding to process because of surface, to ensure that face oil mates with the size of base oil, the resin plate for needing the picture and text of precise restoration to be used preferably uses the resin plate with aluminum base basis.
Step 3, forms frosted ink effect after UV solidification.
The composition of embodiment three: UV base oil is as follows according to mass percent: polyester chloride 40%, epoxy acrylic resin 10%, polyester 22%, photosensitizer 3%, polymerization inhibitor 0.2%, silica sand powder 8%, wax powder 6%, superfine talcum powder 6%, organosilicon auxiliary agent 4.8%；The composition of UV face oil is as follows according to mass percent: epoxy acrylic resin 24%, polyurethane acrylic resin 10%, acrylic monomers 50%, photosensitizer 12%, polymerization inhibitor 0.1%, and organosilicon auxiliary agent 2% shrinks auxiliary agent 1.9%.Base oil dough-making powder oil usage ratio is 1:1.5.
Step one, uses offset printing PS plate print couple in printed on paper First frosted UV base oil.
Step 2, prints second UV face oil in soft version mode on offset press glazing seat.Glazing seat needs to make the flexible resin plates of corresponding document, glazing seat uses chambered doctor blade to coordinate the mode inking of anilox roll, the generally anilox roll that needs depending on sand sense needs design in the range of 80-120 line/cm, resin plate is that flexible fat composition needs the cissing reducing 0.2-0.4mm in offset printing file basis surrounding to process because of surface, to ensure that face oil mates with the size of base oil, the resin plate for needing the picture and text of precise restoration to be used preferably uses the resin plate with aluminum base basis.
