Google translated for me "Could someone tell me how to convert an illustration in Photoshop 2021 from RGB to CMYK

without losing the brightness and intensity of the colors? when I convert it for printing the colors change completely."

Hi, unfortunately the intensity of colour and tone which can be produced using ink on paper generally doesn’t match the intensity of colour and tone which can be viewed on a monitor screen.

Careful optimisation of RGB colour is needed to be sure that when it is converted it will survive.

A calibrated profiled screen is the place to start, then I would work on images in Photoshop and use gamut warning ( a basic but useful tool) and soft-proofing to assist image optimisation.

If you make a piece of music that cvan only be played well by a good orchestra, a small band, no matter how skilled cannot reach the same range of expression.

 

Google again, unfortunately I don't speak Spanish, much as I would love to:

 

Hola, desafortunadamente, la intensidad del color y el tono que se puede producir usando

tinta sobre papel generalmente no coincide con la intensidad

del color y el tono que se puede ver en la pantalla de un monitor.

 

Se necesita una optimización cuidadosa del color RGB

para asegurarse de que cuando se convierta sobrevivirá.

 

Una pantalla perfilada calibrada es el lugar para comenzar,

luego trabajaría en imágenes en Photoshop y usaría advertencia de gama

(una herramienta básica pero útil) y pruebas en pantalla para ayudar

a optimizar la imagen.

 

Si haces una pieza musical que solo una buena orquesta

puede tocar bien, una banda pequeña, por muy hábil

que sea, no puede alcanzar el mismo rango de expresión.

 

 

espero que esto ayude

It does answer the question.

 

CMYK is based on actual physical printing inks on actual physical paper. Each CMYK profile characterizes a specific offset print process.

 

There are limits to how saturated colors you can get with 4 color printing inks. That's why you see some colors desaturate. It has nothing to do with photoshop; just the physical properties of printing inks.

Hola Susana. Siempre que pases de RGB a CMYK vas a perder saturación de colores por que la gama o rango de colores CMYK es mucho más limitado que RGB. Personalmente, cuando voy a trabajar con un documento RGB que va ser convertido a CMYK, desde el inicio del proceso activo la previsualización en CMYK seleccionado View o Vista > Proof colors o Colores de prueba, de esa manera, desde el inicio, sé qué colores voy a obtener cuando haga la conversión a CMYK.

That’s a good policy Marliton.

Soft-Proof can be very useful on a calibrated profiled display as it does well at predicting output.

BUT of course we need a CMYK ICC profile that truly represents the destination device 

 

Esa es una buena política, Marliton.

Soft-Proof puede ser muy útil en una pantalla perfilada calibrada, ya que lo hace 
bien para predecir la salida. PERO, por supuesto, necesitamos un perfil CMYK ICC que realmente
represente el dispositivo de destino

 

I hope this helps

Así es, es necesario un perfil de color, pero dar una explicación de todo el flujo CMS en una respuesta a un post es poco realista. Por ejemplo, de poco sirve el perfil si no se ha realizado una previa caracterización de los dispositivos de entrada y salida o si el perfil no está actualizado. La pregunta original fue simplemente "cómo evitar perder el brillo".

Old, in English (sorry OP) but not too much has changed over the years.

The best and easiest answer provided eariler:

"BUT of course we need a CMYK ICC profile that truly represents the destination device"

Not always easy to get and beware of outside printers who simply tell you "Covert to SWOP" or similar. Maybe yes, maybe no.

Yep DigitalDog, totally agree, some stadards based ICC press profiles are very good, but SWOP aint one.
