A colour image processing apparatus comprising: first obtaining means arranged to obtain monochromatic correction data, using results of measurement of colours of monochromatic patch images, each patch image being formed by an image forming means using only a monochromatic recording material; second obtaining means arranged to obtain multi-colour correction data, using results of measurement of colours of multi-colour patch images, each patch image being formed by the image forming means using at least two colour recording materials; first processing means arranged to first execute a correction process using the multi-colour correction data obtained by the second obtaining means and then to execute a correction process using the monochromatic correction data obtained by the first obtaining means ; second processing means arranged to, in a case that the image forming means forms a colour image, execute the correction process using the monochromatic correction data obtained by the first obtaining means and not the multi-colour correction data obtained by the second obtaining means ; and control means arranged to selectively implement the first processing means and the second processing means , in the case that the image forming means forms the colour image; wherein the control means makes a first setting for a copy job for at least the correction process which is to be executed by the first processing means or the correction process which is to be executed by the second processing means via an operation unit; and wherein the control means makes a second setting for a print job for at least the correction process which is to be executed by the first processing means or the correction process which is to be executed by the second processing means via the operation unit. first obtaining means arranged to obtain monochromatic correction data, using results of measurement of colours of monochromatic patch images, each patch image being formed by an image forming means using only a monochromatic recording material; second obtaining means arranged to obtain multi-colour correction data, using results of measurement of colours of multi-colour patch images, each patch image being formed by the image forming means using at least two colour recording materials; first processing means arranged to first execute a correction process using the multi-colour correction data obtained by the second obtaining means and then to execute a correction process using the monochromatic correction data obtained by the first obtaining means ; second processing means arranged to, in a case that the image forming means forms a colour image, execute the correction process using the monochromatic correction data obtained by the first obtaining means and not the multi-colour correction data obtained by the second obtaining means ; and control means arranged to selectively implement the first processing means and the second processing means , in the case that the image forming means forms the colour image; wherein the control means makes a first setting for a copy job for at least the correction process which is to be executed by the first processing means or the correction process which is to be executed by the second processing means via an operation unit; and wherein the control means makes a second setting for a print job for at least the correction process which is to be executed by the first processing means or the correction process which is to be executed by the second processing means via the operation unit. <EOS>
