by plotting my data to a greyscale map the output is a coarse, chessboard type result (Origin 6.0). Increasing the number of levels in colormap/contours does not help to overcome the problem. Data are are regular converted to the matrix since the are sampled by a CCD. However, other concersion methods did not improve the result.
1. Create a greyscale map. 2. Turn Speed mode off as described above. 3. Click the Save Template button on the Standard toolbar and OK the resulting prompt.
