the running direction of the press. |
| 3. |

| 5. |
The
ink used for proofing should match the colour set established
for the press. Proofing houses can obtain quantities of
the required process colours from the South China Morning
Post at cost. |
| 6. |
Proofs
that do not meet the basic criteria outlined above will
be misleading. South China Morning Post will not be held
responsible for the results of proofs that are unsuitable
for press reference. |
