I am running Arcmap 10.5.1 and have produced a sharpened 3 band Landsat composite image using using the Gram-Schmidt function in Windows->Image Analyses. The sharpened composite image comes up very well on the screen. The problem comes when I try to print the map, the Landsat image part comes out blank. Also, when I try to zoom in the image disappears. Also, I have tried to export the image data to a new location but I get the error message "General function failure - No spacial reference exists". I have checked in properties and the image does have a spacial reference.
