The simplest approach to creating a black and white image is taking a color image and converting it
to grayscale in a photo imaging program such as Photoshop. In addition, although converting an
image from color to grayscale is easy, the opposite operation is complex, in this case it is better to
have it in color. If your image is already converted, you only have to bypass the section 5.
Gray reproduction is dependant on various factors and/or environmental conditions, these conditions
can cause the gray to appear as if it has different colored tones. For this reason we have created
multiple profiles that match many different environmental conditions, so that you can choose the exact
gray reproduction you prefer. Therefore, if you follow this guide instructions and you have problems
