PURPOSE:To produce the title glass panel having excellent mold release after molding and color developing property by forming a ceramic color ink calcined layer consisting of specified base print film layer and overcoat print film layer on a glass substrate. CONSTITUTION:A ceramic color ink having sufficient calcining performance to a glass sheet 1 at a calcining temp. 10-100 deg.C lower than the bending temp. of the glass sheet 1, having good adhesion to the overcoat print layer 4, and developing a desired color when the ink is seen through the glass sheet is formed on the desired region of the float glass sheet 1 consisting of the soda- lime silicate glass having 550-750 deg.C bending temp. to form the base print film layer 3 having 1-100mum thickness. A ceramic color ink having a calcining temp. 10-80 deg.C higher than the bending temp. of the glass sheet 1 and facilitating the release of the glass sheet 1 from a forming die when the glass sheet 1 is bent with the use of the forming die is printed to form the overcoat print film layer 4 having 0.1-50mum thickness on the layer 3, and the ink is heated and calcined to form a ceramic color ink printed layer 2.
