Abstract
A method of screen printing a design on a substrate, the method comprises the steps of controlling a computer-controlled plotter to cut an outline of the design into stencil material the stencil including a perimeter. Then, registering the perimeter of the cut stencil with marks on a printing screen and securing the cut stencil to the printing screen. Then, positioning the printing screen and cut stencil on the substrate and applying ink through the printing screen and stencil onto the substrate, wherein the design is reproduced on the substrate.
Claims8
A screen-printing apparatus comprising:
- a platen upon which a substrate is disposed for screen printing;
- an outer frame disposed above the platen, wherein relative movement between the platen and outer frame brings them into contact;
- an inner frame mounted for rotation within the outer frame, the inner frame carrying a screen, wherein the inner frame and screen are rotatable between a first position in which the screen is disposed for printing and a second position in which the screen is disposed for application of a stencil, wherein the inner and outer frames are generally rectangular and include a pair of opposing side members and top and bottom members;
- a pair of pivot pins, each of the pivot pins extending between the side members of the inner and outer frames, wherein the inner frame pivots about the pivot pins and rotates relative to the outer frame;
- and
- a removable stop pin extending between the top members of the inner and outer frames to secure the inner and outer frames against rotation therebetween.
A screen-printing apparatus comprising:
- a platen upon which a substrate is disposed for screen printing;
- an outer frame disposed above the platen and movable into and out of contact with the platen, the outer frame being generally rectangular and including a pair of opposing side members and top and bottom members;
- an inner frame rotatably mounted by a pair of pins within the outer frame, the inner frame carrying a screen, wherein the inner frame and screen are rotatable between a first position in which the screen is disposed for printing and a second position in which the screen is disposed for application of a stencil, the inner frame being generally rectangular and including a pair of opposing side members and top and bottom members;
- and
- a stop pin between the top members of the inner and outer frames, the stop pin operable to secure the inner frame in at least one of the first and second positions and to secure the inner and outer frames against rotation therebetween.
A screen-printing apparatus comprising:
- a platen upon which a substrate is disposed for screen printing;
- a print screen assembly disposed above the platen, wherein relative movement between the platen and print screen assembly brings them into contact, the print screen assembly including:
- an outer frame;
- an inner frame mounted for rotation within the outer frame, the inner frame carrying a screen, the inner and outer frames being generally rectangular and including a pair of opposing side members and a pair of end members joining the side members;
- a pair of pivot pins, each of the pivot pins extending between the side members of the inner and outer frames, wherein the inner frame pivots about the pivot pins and rotates relative to the outer frame between a first position in which the screen is disposed for printing and a second position in which the screen is disposed for application of a stencil;
- and
- a removable stop pin extending between the end members of the inner and outer frames to secure the inner and outer frames against rotation therebetween.
