Promts
Los prompts son instrucciones detalladas en texto que le indicas a una Inteligencia Artificial (como ChatGPT o DALL-E) para guiar exactamente el estilo, nivel de detalle, contraste y acabado que deseas que genere en una imagen. En el fotograbado láser, un prompt bien optimizado marca la diferencia entre una imagen plana y un grabado limpio, profundo y de alta calidad visual.
Prompts con Fondo Blanco (Ideales para Madera y Materiales Claros)
Estos prompts están diseñados para generar un marcado directo sobre fondos claros o neutros. Al integrar un fondo blanco puro, el software del láser procesa únicamente los trazos, sombras y tramados del diseño, manteniendo la textura natural del material intacta alrededor de la figura.
-
Materiales recomendados: Madera (MDF, triplex, pino), MDF lacado claro, cuero natural, cartón comprimido y piedra clara.
-
Ventaja principal: Preserva el contraste natural donde las sombras quemadas por el láser resaltan directamente sobre el fondo limpio del material.
1. Retrato estilo Grabado de Billetes
Convert this photo into a banknote engraving style portrait on a plain white background. Extremely detailed etched lines, cross-hatching shading, high contrast black and white. The background must be completely removed and replaced with a solid, pure white backdrop, laser engraving ready.
2. Ilustración con Tramado B&N (Dithering)
Convert this photo into a high contrast black and white dithering illustration with a fine dot pattern shading on a plain white background. The entire backdrop must be completely replaced with a solid, clean, pure white background, optimized for laser engraving.
3. Dibujo a Carboncillo
Convert this photo to a charcoal drawing with high contrast sketch and sharp pencil lines on a plain white background. The image must have no original background and no textures on the canvas, showing only a minimalist sketch style on a solid pure white background.
4. Arte Lineal (Line Art)
Convert this photo into a high-contrast black and white line art engraving with ultra-detailed outlines and clean vector style strokes on a plain white background. No background details or original backdrop elements must remain. Solid pure white background, laser engraving optimized, strong contrast, minimal grayscale, sharp edges.
5. Boceto a Lápiz Hiperrealista
Convert this photo into a hyper-realistic pencil sketch with detailed graphite shading and strong edges on a plain white background. High contrast black and white. The background must be completely clear, solid, pure white, and optimized for laser engraving.
Guía de Prompts de IA para Fotograbado Láser en negativo
Diseñados para aislar completamente al sujeto con canal alfa (sin píxeles de fondo), estos prompts permiten trabajar en modo invertido o negativo. Al grabar en acrílico o materiales oscuros, las zonas marcadas por el láser se vuelven blancas o despulidas, mientras que las áreas transparentes conservan el tono oscuro de la base.
-
Materiales recomendados: Acrílico transparente (ideal para rotulación con luz LED), vidrio, metal pintado de negro, mármol/granito negro y plásticos oscuros.
-
Ventaja principal: Optimiza el recorrido del cabezal láser al no escanear fondos vacíos, logrando un efecto de "figura flotante" con alto impacto visual y sin marcas innecesarias.
