600ppi magnified print analysis
HP Photosmart 7350 vs Lexmark Z65
Here we pull back from 2400ppi and reduce magnification buy scanning at 600ppi using the HP Scanjet 7450C. The reproduced selections represent just under 18mm in width from the original 7.5 inch wide prints.
Once again the HP Photosmart 7350 is impressive. The colours are right, definition is retained well and there is no overbearing screen pattern.
By contrast, the HP Photosmart 1315, using the older three colour print head, has a strong red bias, visible grain and corresponding lack of detail.
The Lexmark Z65 fairs little better at 600ppi. The sharpness of the grain simply cannot be ignored and the overall tone is flat and grey. The only saving grace is that detail retention is reasonably good.
Undeniably, the new-technology HP Photosmart 7350 beats the Canon S820D in technical terms (above). At 600ppi the characteristic vertical stripes of the Canonís half-tone screening remain all too visible. When viewing actual prints, however, there is little to choose between the two, however.
