    Hmm personally i find it too demanding for the kit lens to be 100% sharp at pixel creeping level. But under good lighting conditions , its probably possible. Use a very small aperture setting , F16 , mount it on a tripod , and set ISO to 100 , and shuttle speed 100 ,UNder good sunny day light , you should get a sharp pic.

    How big do you intend to print? Why is there a need to examine your photos at 100%? How do you evaluate your photos? Why are you even looking at a minute portion of the photo? Fact is, nothing out there will give you satisfactory results if you look at your photos at 100%.

    and some misconception here and there..... stopping down the lens will yield deeper depth of field, meaning a larger portion of your photos will be in focus, not necessarily sharper.

    Excessively small apertures (large F stop) will result in less sharp images due to diffraction... For many lens the sweet spot is actually no higher than F8 or so but of course varies from lens to lens. Using a smaller aperture still of course give you better DOF, so if you are trying to focus on say a sign board tilted at sharp angle to you, a smaller aperture will surely help.

    How to get sharp pictures:

    1. Steady your camera before pressing shutter

    2. Use a tripod if necessary

    3. Use higher shutter speed; may result in less DOF

    4. Smaller aperture give better DOF e.g. F16 or F11

    5. Higer ISO will give higher shutter speed but may result in more noise

    6. Use camera/lens with Image Stablisation

    7. Try using Center Weighted instead of Multi-Point Focusing

    8. Use good lenses

    9. Check your eyes.

    Actually for kit lens, it won't be that sharp.
    In many cases, if you pixel peep, you won't get very good results in terms of sharpness.
