Material for examination.

Four photographs of a female child, aged 3 - 4 years, wearing a short sleeved pink shirt with white spots, in two different poses (two photos of each pose). Note : PT = posicao.

Examination of the photographs to determine the following:

1. Age of the photos, from the age of the paper and/or the ink used
2. In what kind of machine is the paper of the photos used (machine for rolled or cut paper).
3. How are the photographs cut, by guillotine or other.
4. If the sizes (of the photos) are standard.
5. If the developing or printing of the photos was done in Portugal or in another country.

Observations and tests carried out.

The examination was carried out in accordance with the current procedures of the Documents Area of this laboratory.

Observation of the document(s) using adequate technical means (stereoscopic magnifying glass, spectral video comparing equipment with different kinds of illumination and different wave compression) to search for the printing methods, analysis of the cut margins and other eventual details.

It was confirmed that these were reproductions produced on Kodak Xtra Life photographic paper, printed by pigment sublimation. It was also noted that the sets of the Kodak Xtra Life markings on the back of the photos are presented at the edges of the photos (see image on page 3). The size of the photos is 10,2 x 15,2 cm (4 by 6 inches) which is one of the standard sizes in photographic reproduction and the cut margins are continuous (see image on page 3).

Given the specific nature of the requirements and the type of document in question (photos printed by pigment sublimation on special Kodak paper) and the non- existence of analytical methods that enable the dating of this kind of document by means of the analysis of "inks" we also consulted that company's representative in Portugal.

In this way, it was possible to ascertain that the type of paper that the photographs were reproduced on has been commercially available for almost two years, having replaced Kodak Picture Maker paper, both for use in photographic development booths as for domestic printers.

The machines installed in photographic development booths use rolled paper which is cut by the machine's own guillotine, for the reproduction of photos. On the other hand, domestic photo printers use sheets of paper, which have margins that are cut by perforation in the case of most models of printers. Lastly, the positioning of the markings on the back of the photos, could indicate that these were printed on a series 47xx machine (in a booth) or using a G600 Dock printer (domestic use).

However, we were told by Kodak that any analysis for the concrete determination of the type of machine used in the printing of the photos, could only be done at their factory in Rochester, US.


Based upon the observations made it is only possible to include the following:

1. The paper used to print the photos in question has been commercially available for almost two years.
1.1. The format of the photos is of 10,2 x 15,2 cm (4 by 6 inches) which is a standard size for photographic reproductions.
1.2. With regard to the cut margins of the photos and the position of the markings on the back, it could be said that they were produced using a 47xx series machine (in a booth) or using a domestic type G200 Dock printer. However, only an analysis by Kodak, in the US, could eventually determine concretely the type of machine used to obtain these reproductions.

Observations: Return the material.

Lisbon, 4th March 2008.
