A coreless thermal transfer recording web rollis formed by rolling a thermal transfer recording weba in a roll. An inner end partof the thermal transfer recording weba of the thermal transfer recording web rollhas a taba formed at a substantially middle of the inner end partand sticking partsb formed on the opposite sides of the taba, respectively. Pseudoadhesive double-coated tapesare attached to the sticking partsb, respectively. The pseudoadhesive double-coated tapes become tack-free after the sticking partsb have been separated from the innermost layer of the thermal transfer recording weba of the thermal transfer recording web roll

The present invention provides a sheet for forming an image having an identifying mark, an image forming method, and an image forming apparatus using the same, wherein the identifying mark is useful to identify various information concerning the sheet. The sheet for forming an image is provided with two or more image-formative layers which are defined by frame respectively and arranged in a longitudinal direction of the sheet. The identifying mark comprises a sequence of mark bits which records the information, and the mark bits are respectively allocated to unit frames each of which comprises a single frame or plural frames of the image-formative layer with the mark bits being arranged in order of the sequence recording the information and repeated at least one cycle period of a certain number of the unit frames along with a longitudinal direction of the sheet for forming an image, wherein the sequence of the mark bits constituting the identifying mark is a combination of a sequence of mark bits constituting a first mark A with a sequence of mark bits constituting a second mark B, the first mark A having a cycle period of a natural number X, the second mark B having a cycle period same as said X or of a natural number Y different from said X and relatively prime with said X.

A printing system according to the present invention includes a media terminal box which may be installed on a street. In the box, there are disposed a measuring device that measures the temperature or humidity in the box, a device such as a CPU, and a storage device. The storage device stores correction data including a correction value based on a combination of the temperature and humidity, and history data relating to the temperature and humidity measured by the measuring device. The control device corrects a color tone of image data which is read out from the storage device based on the temperature/humidity history data and the correction data so as to generate corrected image data. The corrected image data is sent to a printer, and then the printer is operated based on the corrected image data.

A thermal transfer printer includes a thermal transfer recording web roll having a bore and obtained by rolling a thermal transfer web. The segment of the thermal transfer recording web forming the innermost layer of the thermal transfer recording web roll is fixed to a part of a segment of the same forming the second innermost layer of the thermal transfer recording web roll. A holding device is inserted in the bore of the thermal transfer recording web roll to hold the thermal transfer recording web roll. The thermal transfer recording web roll and the holding device rotate in a unit to feed the thermal transfer recording web to a thermal transfer recording unit that forms images on the thermal transfer recording web. The thermal transfer recording web roll can be prepared at a low cost without requiring much time and effort.
