Hi,
you have to specify a compression method using TIFF_Compression property.
For color images you can select ioTIFF_LZW, ioTIFF_JPEG and ioTIFF_PACKBITS (and other two non standard ways).
Example (a single page in TImageEnView):

ImageEnView.IO.Params.TIFF_Compression := ioTIFF_JPEG;
ImageEnView.IO.Params.SamplesPerPixel := 3;
ImageEnView.IO.Params.BitsPerSample := 8;
ImageEnView.IO.SaveToFile('output.tiff');
