Zusammenfassung:PROBLEM TO BE SOLVED: To provide a thermal transfer printing method and a thermal transfer printing device that reduce the running cost for an ink ribbon by an n-fold mode and also form images of good quality on photographic paper.SOLUTION: An ink ribbon 5 including a dye layer and photographic paper 7 are put one over the other and conveyed between a thermal head 1 and a platen roll 2, and the thermal head 1 heats the ink ribbon 5 based upon image data and transfers dye to form an image on the photographic paper 7. A method comprises the processes of: finding a first magnification of a conveyance speed of the photographic paper 7 to a conveyance speed of the ink ribbon 5 based upon a type of the ink ribbon 5; finding a second magnification of a conveyance speed of the photographic paper 7 to a conveyance speed of the ink ribbon 5 based upon the image data; and determining a conveyance speed of the photographic paper 7 and ink ribbon 5 based upon the first magnification and second magnification, and conveying the photographic paper 7 and ink ribbon 5 at the determined conveyance speed to form the image on the photographic paper 7.SELECTED DRAWING: Figure 1 【課題】n倍モードによりインクリボンのランニングコストを削減すると共に、印画紙に良質な画像を形成する熱転写印画方法及び熱転写印画装置を提供する。【解決手段】染料層を含むインクリボン5及び印画紙7を重ね合わせて、サーマルヘッド1とプラテンロール2との間を搬送させるとともに、サーマルヘッド1が画像データに基づいてインクリボン5を加熱し、染料を転写して印画紙7に画像を形成する。インクリボン5の種類に基づいて、インクリボン5の搬送速度に対する印画紙7の搬送速度の第1倍率を求める工程と、画像データに基づいて、インクリボン5の搬送速度に対する印画紙の搬送速度7の第2倍率を求める工程と、第1倍率及び第2倍率に基づいて、印画紙7及びインクリボン5の搬送速度を決定し、決定した搬送速度で印画紙7及びインクリボン5を搬送して印画紙7に画像を形成する工程と、を備える。【選択図】図1
