The invention provides a thermal printing control method and a thermal recording device. The method comprises the steps of S1, reading black and white binarization information required for recording and data information corresponding to gray level harmonization information through the thermal recording device separately; S2, taking out maximal and minimum values from data values of the gray levelharmonization information with the bit depth, transforming '0' in the black and white binarization information into the minimum value, and transforming '1' into the maximal value; S3, conducting datareconstitution, wherein printing data with the bit depth is preserved for each printing point within the area range of {(1,1), (N,M)}, and data of the gray level harmonization information is within the specified area range of {(n+1,m+1), (n+n1,m+m1)}; S4, transforming the data formed in S3 into printing data, and then forming several printing sequences; S5, conducting printout. By means of the method, the black and white binarization information required for recording and the gray level harmonization information in the specified area can be printed simultaneously in the one-time printing process of the same thermal sensing medium.

The method provides a 2.5D image printing method capable of accurately restoring and printing an original manuscript. Significant information in the original manuscript is extracted in a multi-level manner in a transformation domain, and height information in different tone positions of the original manuscript is simulated and printed out in multi-level extraction and overprinting modes, so that the 2.5D image printing method has the advantages of automatic extraction, rich levels, high self-adaption, high restorability and the like. Compared with an existing 2.5D printing method, the 2.5D image printing method has the advantages that the height information in the original manuscript can be automatically simulated and extracted through a computer, a tedious printing pre-processing process is avoided, further, restorability for tone levels is higher, rich information in the original manuscript can be accurately reproduced, and the 2.5D image printing method has certain artistic value in the field of printing reproduction of a few special original manuscripts.

2.5D image printing method

An image processing apparatus includes: one or more than one sensing means (101, 102, 103, 105) that senses an event on the image processing apparatus; a first memory means (24); a main CPU (124b) that loses power supply while sleep mode is on; and a subordinate CPU (124a) that receives power supply even while sleep mode is on. The subordinate CPU (124a) performs: terminating sleep mode; judging whether not an event occurs on the image processing apparatus, by inquiring of the one or more than one sensing means (101, 102, 103, 105), at predetermined intervals during the transition of the main CPU (124b) from sleep to normal operation; and storing a record of an event on the first memory means (24) if it occurs. After the transition, the main CPU (124b) retrieves the record from the first memory means (24) and performs processing using it.

A seal carving apparatus (10) includes a thermal head (12) having a plurality of heat generating elements (12a) disposed in lines, and thermal drive control means (24) that performs a control process of selectively and thermally driving the individual heat generating elements while moving the thermal head and a porous material in relative to each other with the thermal head (12) being in abutment with the porous material, thereby forming a seal face on the porous material. The thermal drive control means (24) controls a pulse time width for thermally driving the individual heat generating elements (12a) of the thermal head under PWM control based on gradation image data having a gradation value, thereby forming a seal with a gradation on the porous material.

PROBLEM TO BE SOLVED: To provide a porous stamp unit for manufacturing a stamp by a thermal head which exhibits an excellent handleability.SOLUTION: A porous stamp unit in which an ink occlusion body 2 is stored in the interior of a box-shaped case body 1 of which a top face is opened, and said opening is covered by a frame body 3 having a porous stamp material 3a comprising a thermoplastic resin. In the porous stamp unit, a separator 4 is removably provided between the porous stamp material 3a and the ink occlusion body 2. The separator performs two actions comprising an action as a shield material which prevents seepage of an ink in the ink occlusion body 2 from a print surface and an action as a pedestal of a thermal head in a case that a print surface is formed on the porous stamp material 3a by the thermal head.SELECTED DRAWING: Figure 1

PROBLEM TO BE SOLVED: To provide a structure of a sheet for label printing, which allows simple preparation of a label displaying the contents of a stamp by using a thermal head-type printing surface processing device.SOLUTION: A structure has a printing sheet 1 and a peeling sheet 2 stacked in a peelable manner with an adhesion layer 3 interposed therebetween. In the structure, the printing sheet 1 can be separated into a label area 10a having a printing part formed thereon and a margin area 10b by a cutting line 1a. Further, on an upper surface of the printing sheet 1, a thermal fusion transfer ribbon 4 having a film structure in which an ink layer 6 is stacked on a base body 5 is bonded to the outside of the label area 10a to be integrally stacked. The thermal fusion transfer ribbon 4 is preferably one that, for example, is bonded to the printing sheet 1 via an adhesive 7 applied to a lower surface peripheral portion of the ink layer 6 to be integrally stacked.SELECTED DRAWING: Figure 2
