AVERTISSEMENT

Risque de perte de la correspondance texte-illustration lors de l'impression papier.

Pour des raisons techniques, il ne peut pas être exclu à l'heure actuelle que, même
en cas d'affichage correct à l'écran, la correspondance entre le texte et l'illustration
puisse être erronée sur l'impression papier.

• 

Si l'erreur passe inaperçue, on court le risque d'exécuter certaines opérations de
manière incorrecte pouvant conduire à des dommages corporels et matériels.

• 

→ Comparez impérativement pour cette raison les impressions papier avec l'affichage à l'écran.
Corrigez-les en cas d'erreur de manière à reproduire correctement l'affichage à l'écran.

ATTENZIONE

Pericolo di perdita dell'abbinamento testo-immagine nella stampa.

Per motivi tecnici non è escluso che, nonostante la rappresentazione sullo schermo
risulti perfetta, durante la stampa venga persa la corrispondenza fra testo e
relativa immagine.

• 

Se tale difetto non viene rilevato vi è il pericolo che i lavori non siano eseguiti
correttamente; ciò può avere come conseguenza lesioni e danneggiamenti.

• 

→ Per questo motivo, dopo la stampa è assolutamente necessario confrontare le stampe con la
rappresentazione sullo schermo. In caso di errore si prega di correggere le stampe, così da
garantire la riproduzione esatta della rappresentazione sullo schermo.

ADVERTENCIA

Al imprimir se corre el riesgo de perder la correcta asignación de las figuras al texto.

Por motivos técnicos, por el momento no se puede descartar que, aun siendo
correcta la imagen que aparezca en la pantalla, al imprimir se pierda la
correlación entre el texto y la figura correspondiente.

• 

Si este error pasara desapercibido, existe el riesgo de que los trabajos no se
ejecuten de forma correcta y, por tanto, se produzcan daños personales y
materiales.

• 

→ Por ello le rogamos que tras el proceso de impresión compare siempre las copias impresas con
la imagen de la pantalla. En caso de error, corrija las copias impresas de forma que se
correspondan con el contenido de la imagen de la pantalla.
