Abstract

The principle of invention of stamp are: 1) pre-assembled before development stamp mount having already fitted - sealed by heat in stamp mount microporous material together with ink reservoir, 2) carbon liquid as light absorbent in light developing process of microporous stamp material. The microporous stamp material surface is covered by dark liquid helping into close porous by light.

Description

PREINKED STAMPS WITH INK RESERVOIR DEVELOPED BY LIGHT or HEAT USING CARBON LIQUID
1. FIELD OF INVENTION.
This invention relate to a hand stamp which is used for imprints on surfaces absorbing or not absorbing ink as paper, textiles, glass, metal, plastic etc.
2. DESCRIPTION OF THE INVENTION.
The invention is in two stages in hand stamp preparation process:
1. Invention I: The Ink Reservoir build in stamp.
2. Invention II: The Carbon Liquid as heat absorbent in stamp exposure process.
INK RESERVOIR BUILD IN STAMP.
The principle of the invention is the Ink Reservoir assambled toogether with microporous flexible material reciving the stamp mount (handle) or Ink Reservoir as a insert part of stamp mount body.
The Ink Reservoir is build in three or two elements as shown on Fig. 1 :
1. Body of Ink Reservoir
2. Insert part - support for microporuous die plate. Above two parts can be made in one piece.
3. Die plate made in microporous flexible material. The body of Ink Reservoir is made of Polyethylene, Polipropylene or other similar plastic material. Assambling of ink reservoir is shown on Fig. 2. The microporous die material is sealed with Ink Reservoir body by heat, glue or microwaves. The easiest way is sealing by heat.
Sealing by heat.
- Sealing machine: in section "sealing machine".
- Recomended sealing temperature should be 170 - 180°C.
- Pressing time recomended: 0,5 - 1 ,0 seconds.
- Press stroke recomended: height.
Sealing machine.
The machine has to be selected to make easy to control following conditions:
- temperature
- pressing time
- pressing power
- distance.
Machines with inaccurate pressing position or weak pressing pressure should not be in use.
The Soldering Tip should be made of heat conducting material souch as Alu, Steel, Brass etc.
During sealing by heat it is recomended to use "Protecting
Folia" between the Soldering Tip and microporous material.
Folia protect the die material and reservoir body material to not stick to the Tip. The moulding temperature of Protection
Folia should be ab. 18O°C.
If Protecting Folia stick to the Tip than it is recomended to treat the Tip with Teflon or similar material.
Soldering Tip has to cover micropourous die material in distance of 0,75 - 1 ,0 mm from the eges.
The dept in the Tip should be 5,0 mm or bigger (Fig. 3).
Sealing Process.
Soldering Tip, reservoir and die material surfaces have to be perfectly horisontal. Otherwise the die plate is not sealed perfect: reservoir is not ink-proof and ink can goes out - stamp is leaking. Sealing time should be short as possible(O,5 seconds) becouse micropourous material can get to hard or burn. DEVELOPMENT OF THE STAMP: EXPOSURE OF THE
STAMP MICROPORUOUS DIE PLATE USING
CARBON LIQUID.
Microporous Die Material with bubbles should be covered by Carbon Liquid which helps to absorb heat from the light during exposure.
The exposure unit should be with build in Xenon bulb emitting needed infrared part of the light.
Carbon Liquid composition.
The Carbon Liquid should be made of following products mixed toogether:
- Ethanol: 98,825% (between 90 - 99%) in composition.
- Carbon: 0,475% (between 0,3 - 2, 1%) in composition.
- Isopropyl Alkohol or 2-Propanol: 0,675% (between 0- 10%) in composition.
- PolMnyl Buthyral resin: 0,025% (between 0,02 - 1 ,0%) in composition.
Procedure of using Carbon Liquid.
Apply the Carbon Liquid onto microporous material surface until is completely black. Within ab. 0,5 - 2 hours Ethanol will evaporate from the Liquid. Other Liquid components will fit sticking to the stamp die material.
On the covered by Liquid surface (between printed image and die material) place OHP Protection Transparent Film or tracing paper, digigraph film or any other film for laser printers or copiers.
Transparent OHP Film prevent die material of to not stick with any tonner from printed image.
Substitutes of Carbon Liquid.
The result as using Carbon Liquid is similar when using White Board Pen, carbon containing ink or any other liquids contain Carbon which can absorb heat from the light. Covered by Carbon Liquid microporous die material can be made of Polyethylene, Polyolephine or Polyurethane. PRODUCTION PROCESS of THE EXPOSURED STAMPS.
The procedure of exposure of the stamp is following:
1. Cover the Stamp Die Micropourous Material with Carbon Liquid. Leave it until it is dry.
2. Printed out, created image place onto already assambled and sealed with die material Ink Reservoir toogether with OHP Transparent Film.
3. Place it toogether into Light Exposure Unit pressing the Die Material.
4. Exposure it one or several times. After exposure the printed image is "transfered" to the die material.
5. Fill the Ink Reservoir with the correct quantity of ink. Seal the inking hoi with plug having air-ascape. Until ink will penetrate the microporous die material use the Stamp Pad or place some ink drops on the top of die material. The stamp is ready for to use.
ADVANTAGES AND BENEFITS OF INVENTION.
1. The Ink Container and Carbon Liquid makes preink stamp imprint top quality.
2. Sealed microporous die material makes not leaking eges of the die plate.
3. Carbon Liquid protect of leaking eges or dotts on microporous material surface.
4. Pre -assambled stamp with already fitted and sealed die material eliminate cutting, glueing, assambling and other boring ways of inking at stamp manufacturing plant.
5. Ink Reservoir makes easier stamp refilling with the ink.
6. Above conditions dramatically reduce Production Time at Stamp Manufacturing Plant. The consequence of time reduction is cost reduction.
7. Pre - assambled stamp: ink reservoir with already fitted in die material, exposure by Light, no glueing, no assambling, no waist, clean production area makes above technology Environmental Friendly.

Claims

1. The ink container build in pre-inked stamp. The stamp filling and refilling by ink is made into container instead of inking directly to material.
2. Microporous stamp material is connected to ink container by heat giving in result ink resistant stamp mount. The sealing is made before stamp developing as stamp exposure by light or any other stamp developing by heat as thermal head.
3. Covering the surface of stamp microporous material by Carbon Liquid Formula or any other Carbon formula helping into absorb heat from light during stamp light exposure process.
