2. Description of the Related Art Conventionally, printing, foaming and embossing are performed on web sheets (continuous long sheets) such as paper and plastic films to produce decorative sheets and wallpaper. In general, the process, the foaming process, and the embossing process are performed in an off-line manner, in which each is manufactured on a separate manufacturing line.

[0003] When printing, foaming and embossing are performed by such an off-line method, a web sheet is first introduced into a printing apparatus before the actual printing, and a normal printing ink for pattern / color printing is used. Trial printing (printing) is performed using a foaming ink (printing ink or ink obtained by mixing a foaming agent in a coating paste). Then, while adjusting the printing conditions such as the predetermined hue, density, film thickness, and printing register, predetermined printing is performed on the web sheet as specified.

[0006] After visually confirming that predetermined printing is being performed, the process shifts to actual printing while maintaining the same conditions. Then, a predetermined print pattern and a foaming pattern are printed on the web sheet and rolled up by the actual printing, and a rolled (rolled) printed matter (web sheet printed matter) is once obtained.

[0005] Next, the obtained printed web sheet is unwound and introduced into a processing device such as a heating device or an embossing device, where the foamable ink is heated and foamed, embossed, and used to form a decorative sheet or wallpaper. Manufacture processed sheets.

[0006] In the above-mentioned off-line method, when processing a printed sheet of a different pattern, a different foaming pattern, or a different embossing pattern over two or more kinds of lots (items), it is necessary to set each lot (item) for each lot (item). Replace the printing plate or embossing roll used for the previous lot with the printing plate or embossing roll used for printing the next lot, perform test printing as described above for each lot, and then After obtaining rolled printed matter for each lot, the printed matter is introduced into a heating device and an embossing device, and subjected to heat foaming and embossing to produce processed sheets such as decorative sheets and wallpaper. ing.

However, in such an in-line system, a heating device and an embossing device other than the printing device are not used during the test printing on the web sheet. Therefore, the heating device and the embossing device are not used until the test printing on the web sheet is completed. It is necessary to temporarily stop the heat source such as to avoid wasteful energy consumption.

[0010] Since the heating device and the embossing device are rotated in conjunction with the printing device, the driving operation system is idle even during test printing on the web sheet, resulting in wasteful energy consumption. I was

However, the repetition of the stop / re-operation of the heat source or the idling operation of the driving operation system consumes wasteful energy other than energy contributing to actual production, so that more efficient production is performed. A system was desired.

An object of the present invention is to avoid repetitive operation of stopping the heat source of the heating device or the embossing device during the trial printing on the web sheet and restarting the heat source in the actual printing, and to avoid wasteful energy consumption due to idle operation. .
