Tout le matériel pour l'impression en DTF


L'industrie de l'impression numérique sur textile a connu une croissance rapide depuis plusieurs années. Il existe plusieurs techniques qui recquièrent ce type de matériel et notamment l'impression Directe sur Film - DTF (Direct to Film Printing).


Qu'est-ce que l'impression DTF?

La technique DTF est aussi simple que son nom l'indique et réside en quelques étapes seulement. Le concept est simple : imprimez sur un film et transférez directement sur tissu. Son principal avantage est de pouvoir réaliser des marquages sur tout type de textiles. Qu'il s'agisse de polyester, de coton, de soie ou de fibres synthétiques, la technique d'impression DTF saura s'adapter.

L'un des atouts de l'impression DTF est qu'elle ne nécessite pas d'investissement financier important ou de pré-requis particulier. Que vous soyez familier avec l'impression numérique et que vous souhaitiez passer à l'impression DTF pour diversifier votre activité, ou alors que vous partiez de zéro, le matériel nécessaire restera le même :

  1. Direct film printers - These printers are often referred to as modified DTF printers. They have basic 6 colour ink tanks such as Epson L1800 etc. This offers convenience as CMYK DTF inks can fit into the standard CMYK tanks while the LC and LM tanks can be filled with white DTF inks. The rollers used to slide the page are also removed to avoid 'doubling up' on the white layer printed on the DTF film.
  2. Films - PET films are used in the DTF printing process. These films are different from those used in screen printing. They are about 0.75 mm thick and have better transfer capabilities. In the market they are often called DTF transfer films. DTF films are available as cut sheets (they can be used for small-scale use) and rolls. Another classification of PET films is based on the type of peeling that is done after transfer. Based on temperature, there are 2 types of film: hot peel or cold peel.
  3. Software - The software is an important part of the process. The print characteristics, colour performance of the inks and final print performance on the fabric after transfer are determined by the software. For DTF printing, specialised RIP software is required that can handle both CMYK and white colours. Colour profiling, ink levels, drop size and other factors contributing to an optimised print result are all governed by the DTF printing software.
  4. Hot melt adhesive powder - DTF printing powder is white in colour and acts as an adhesive material that binds the coloured pigments of the print to the fabric fibres. There are different grades of DTF hot melt powders which are specified in microns. An appropriate grade should be chosen according to the requirements.
  5. DTF printing inks - These are pigmented inks specially designed for this technique and available in the colours cyan, magenta, yellow, black and white. The white ink is a special component that is deposited on the film and on which the coloured design is printed.
  6. Automatic Powder Agitator - This is used to apply the powder evenly and also to remove excess powder.
  7. Curingoven - It is essential to use a small industrial oven to melt the hot melt powder applied to the transfer film. A heat press can be an alternative for this operation, but it must be used in non-contact mode.
  8. heat press - The heat press is used to adhere the image printed on the film to the fabric. It can also be used to heat the hot melt powder on the DTF film as explained above.

Les étapes de l'impression

Étape 1 - Impression sur film
Au lieu d'utiliser un papier ordinaire, insérez le film PET dans les bacs de l'imprimante. Vous devez paramétrer dans votre logiciel l'impression des couleurs en premier. La couche de blanc vient s'imprimer par dessus les couleurs sur votre film PET. Un point également important à retenir est que l'impression sur le film doit être une image miroir de l'image réelle qui doit apparaître sur le tissu.

Étape 2 – Poudrage
Cette étape consiste à appliquer la poudre thermofusible sur le film contenant l'image imprimée. La poudre doit être appliquée uniformément lorsque l'impression est humide. Veillez à éliminer l'excès de poudre doit être soigneusement élimininé.Une façon simple de s'assurer cela est de maintenir le film sur ses bords courts de sorte que ses bords longs soient parallèles au sol (orientation paysage). Il faut verser la poudre au milieu du film de haut en bas de sorte qu'elle forme environ un tas d'un pouce d'épaisseur au centre, du haut vers le bas. Récupérez le film avec la poudre et pliez-le légèrement vers l'intérieur de sorte qu'il forme un léger U avec la surface concave tournée vers soi. Maintenant, secouez très légèrement ce film de gauche à droite pour que la poudre se répande lentement et uniformément sur toute la surface du film. L'une des alternatives est d'utiliser des agitateurs automatisés disponibles pour les configurations commerciales .

Étape 3 - Faire fondre la poudre
Cela peut être fait de plusieurs façons. Le moyen le plus courant consiste à placer le film avec l'image imprimée et la poudre appliquée dans le four de polymérisation et à les chauffer. Si cela n'est pas possible, utilisez une presse à chaud et rapprochez le haut de la presse du film sans le toucher. Il doit y avoir un espace d'environ 4 à 7 mm entre le film et la plaque supérieure de la presse à chaud. On peut utiliser un fil métallique pour fixer le dessus de la presse de sorte qu'elle ne se referme pas totalement sur le film et laisse un espace nécessaire. Pour de meilleurs résultats, il est fortement recommandé de suivre les spécifications du fabricant pour la fusion de la poudre. En fonction de la poudre et de l'équipement, le chauffage se fait généralement pendant 2 à 5 minutes avec la température autour de 160 à 170 degrés Celsius.

Étape 4 - Pré-pressage
L'étape consiste à pré-presser le tissu avant le transfert de l'image par le film pendant 2 à 5 secondes. Cela permet d'aplatir le tissu et d'assurer également la déshumidification du tissu. Le pré-pressage permet un transfert optimal de l'image du film sur le tissu.

Étape 5 – Transfert
C'est le cœur du processus d'impression DTF. Le film PET avec l'image et la poudre fondue est placé sur le tissu pré-pressé, dans la presse à chaud. Ce processus est également appelé «durcissement». Le durcissement est effectué à une température de 160 à 170 degrés Celsius pendant environ 15 à 20 secondes.

Étape 6 - Peeling à froid
Il est important que le tissu et le film maintenant adhéré, refroidissent à température ambiante avant de retirer le film. Une fois le film refroidi, il doit être décollé du tissu.

Étape 7 - Post-pressage
Il s'agit d'une étape facultative mais très fortement recommandée pour de meilleurs résultats. Elle permet d'obtenir des meilleures performances telles que la résistance au lavage et au frottement. Dans cette étape, le textile avec le motif transféré est pressé dans la presse à chaud pendant environ 10 à 15 secondes.

Avantages de DTF :

  1. Works with almost all types of fabrics
  2. Does not require pre-treatment
  3. Excellent wash resistance
  4. The fabric has a very light touch
  5. The process is faster and less time-consuming than DTG printing

Compared to sublimation printing, the colour vibrancy is less dense.

Créadhésif currently offers quality DTF inks that are compatible with most DTF printers. Our inks are particularly well known for their ability to bring out the most delicate colours on light and dark coloured fabrics. The white gives the printed colours an appropriate density with optimum ink consumption.

In general, it can be said that DTF printing allows you to get rid of almost all the constraints that are often encountered in other textile printing techniques. The versatility of the textile materials on which it is possible to work is a real advantage. Since pre-treatment is not essential, in many cases the overall cost of printing is reduced, thus offering a higher profit margin. In conclusion, DTF printing can be considered the best solution for textile marking.
