Abstract

PURPOSE:To correctly see a character or a figure through the front surface by printing an inverted character or an inverted figure with normal printing ink on the back surface of a normal sheet, and forming the front surface transparently or translucently. CONSTITUTION:A character or a fiture on the back surface can be seen through merely by using a normal printing ink 2 on the back surface of the sheet and printing the front surface with transparent ink 3. Thus, the character or the like is normally printed on the back surface and the ink 3 is printed from the front surface, but the ink 3 may be printed on the back surface of the sheet 1 and the character may be printed thereon with normal ink 2. Further, even when the ink 3 is printed on the front surface, or when transparently printing ink is printed on the printed character, the same object and effect can be attained.

Description

Detailed Description of the Invention "Industrial Applicability!'?" The present invention relates to a printing method for wrapping paper, office paper, envelopes, etc., which is used by printing on paper.

Conventional technology When characters printed on the back side of word paper can be seen through from the front side, the back side of the paper has been previously treated to make it transparent. In addition, the ink required a specially formulated ink, which required time and money.

``Problem to be solved by the present invention J'' In the present invention, reverse characters and reverse figures are printed on the back side of ordinary paper using ordinary printing ink, and the surface is made transparent or semi-transparent. , is a printing method that allows characters and figures to be accurately seen through the surface, and eliminates the conventional complicated and expensive process.

Means for Solving Problems J The embodiment of the present invention will be explained with reference to the drawings.Reverse characters or reverse characters are printed on the back side of paper 1 such as wrapping paper, 21S office paper, etc. using ordinary printing ink 2. It prints orientation figures, etc., and prints transparent printing ink 3 on the front surface, making part or all of the back printing transparent or semi-transparent so that it can be read visually from the front surface. It is something.

ζ Function The present invention is characterized by the above method, and the paper used may be ordinary paper. Just use normal printing ink on the back side of the paper and simply print with transparent ink on the front side.
You can see through the text and graphics on the back. Therefore, the characters are printed on the inside, and there is no wear of the print from the surface. In addition, in the case of wrapping paper, the wrapped contents can be seen through, which is convenient. Furthermore, paper and ink do not require special processing steps in advance, so they are inexpensive and easy to process. Furthermore, since the ink is for normal printing, it is possible to recycle used paper, and even when incinerated, it does not generate toxic substances and does not generate high heat during incineration, so it does not cause any damage to the furnace, is non-polluting, inexpensive, and can be produced in large quantities. This is something that can be provided.

``Example J In the water head example, letters etc. were normally printed on the back side and transparent printing ink was printed on the front side, but as shown in Figure 2, transparent printing ink 3 was printed on the back side of paper 1, and the You can also print the letters on the north side with ordinary printing ink 2. Figure 3 shows the case where transparent printing ink 3 was also printed on the surface, and figure 4 shows the case where transparent printing ink was printed on the letter printing. In either case, the objective effect of the present application can be achieved.

``Effects of the Invention'' According to the present invention, reverse characters or reverse direction are printed on the back side of ordinary paper using ordinary printing ink, and
By printing the paper with transparent ink to make the surface transparent or semi-transparent, it can be seen through the surface normally, so printed characters do not wear out, are easy to manufacture, can be provided at an extremely low cost, and can be recycled after use. This has the advantage that it does not cause the same pollution during treatment or incineration.
