The retail pressing is slightly different to the promotional pressing. The discs were pressed by different pressing plants, and the matrix codes are different as a result. The first pressing discs' titles were printed in color. The second pressing added a -2 suffix to the catalog number and different text font on the front insert. The suffix does not mean it is a second pressing, it simply means that it is a CD. Similarly, a vinyl release would have had a -1 suffix, while a cassette would have had -4. These are common numbers used in the industry.
