4	I see alot of differences in all three lineart images. The low dpi seems to be very blurred and not very readable. 300 dpi is a little better giving the image more definition.  The higher dpi shows more details giving you a clearer image with more detail and shade. The grayscale like the line art is very clear to see the difference between the images.  The 75 dpi leaves it quite blurred around the edges. The 300 takes quite a bit of that away but is still left with a rough edge. The 1200 seems too smooth, these defined edges give a clear image but I almost feel it’s on the verge of being too bright. I was surprised with the image drawn on the serviette. I thought it would come out as solid black lines but the higher resolution has shown the inconsistency coming from the ink in the pen and though it wasn’t visible to me at first it has brought out these details in the scan. The lower the dpi the lower the file size and resolution of images. When scanning at 300 dpi it appears to be the right balance between the high and low leaving you with a reasonable file size and standard definition.  1200 will give you higher resolution and higher file size. I think it all depends on what type of picture you are scanning and what you are using it for to what settings and dpi you will use.
